    I find the font/colour combinations make posts a bit hard to read sometimes.
    1. The title colour for comments and times is a light grey, while the colour of comment text is a darker grey. These can be hard to read against a white background. With occasional exceptions, non-coloured text against a white background should be black for maximum contrast.
    2. Distinct comments should be visually separated from each other somehow, either by a horizontal bar or by using a different background colour for comment headers. (The latter is what is done, for example on Slashdot).
    Presently, any links outside of the Maple Primes site open in the same window. Would it be possible to have the external links open in a different windows. This way once done viewing the external link the window can be closed and there is still a Maple Primes session window open. Presenly, one must backspace out of the external site to get back to Maple Primes. Any thoughts on this? JB
    According to the information on message formatting, all posts are formatted using HTML tags. This will prove problematic for people posting snippets of Maple input, which is likely to happen often. For example: ========================================================= > p := piecewise(x
    This post is primarily a test of attaching pictures and documents within the environment. If this works, you should see a photo of the view from our rental apartment during my family's recent holiday in Tuscany, and you should be able to access a Maple document via the attachment. Any problems in viewing or detaching, contact me. Any questions on the apartment, see www.toscanacasevacanza.com.
    The XML icon for the site's RSS feed appears on the left-hand side of the screen, and the feed works when I add it manually as a Live Bookmark in Mozilla Firefox. So the site is certainly capable of RSS feeds. However, I think the convention is that sites with RSS should also advertise this fact by adding metadata to the page header, which MaplePrimes doesn't yet do. An example of this metadata is: <link rel="alternate" type="application/rss+xml" title="RSS 2.0" href="http://examplesite.com/feed/" /> <link rel="alternate" type="text/xml" title="RSS .92" href="http://examplesite.com/feed/rss/" />
    I'm not sure what the snail-mail addresses are going to be used for. In any case, if they're going to be requested, it would be helpful to include a field for province/state information there. We currently have just "City" and "Country". As it is, there isn't enough information to create a mailing address from what's provided. (There's actually a Waterloo, Quebec, as I'm reminded of every time I go to theweathernetwork.com site.)
    Might it make better sense to have the 'Home' and 'About' site navigation tabs in the top right of the page to be reversed?
    It would be nice if the site could remember the login information, so that we don't have to log in every time.
    In some applications it is necessary to map an angle to a range of 0 to 360 degrees. Adding 360 degrees to an angle, or subtracting 360 from an angle does not change actually change the angle. One way to do this would be to add (or subtract) enough multiples of 360 degrees until the angle falls between 0 and 360. For example, given an angle of 400 you would subtract 360 to get an angle of 40 degrees. In Maple, this is easily accomplished by the following function.

    Frem := (x,y) -> x - y*floor(x/y);

    Yesterday, I was in a Maplesoft management meeting where we concluded that the launch of MaplePrimes was to become the number one (or maybe two) priority for the company. So here it is ...

    Solitary waves, or solitons were first described by Scott Russell, who noted the phenomenon while riding alongside a canal in 1834. He described a peculiar wave in the canal wave a single well-organized heap that propagated, seemingly without dissipation, for several miles. As a naval designer, Scott recognized that there were important things to be learned from these unusual waves.

    The rules for using MaplePrimes are simple: Respect each other and behave. Use common sense and your time on MaplePrimes will be fun and productive.

    1. MaplePrimes does not allow obscene, racist, homophobic, or sexually explicit language. We reserve the right to remove postings that defame or insult anyone, as well as posts that are abusive or hateful. Any harassing posts or postings that might be construed as stalking will be deleted and made available to the proper law-enforcement officials.

    Here is an example to illustrate the problem.
      
     > y := SQRT(4);
                                       y := SQRT(4)
    
    To get the square root function, you must use the name "sqrt", because Maple is case sensitive. Other examples of this are:
    • use "Pi" rather than "pi" to get 3.141etc
    • use "exp(1)" rather than "e" to get 2.718etc
    • use "I" rather than "i" to get the square root of minus 1
    Also note that, for example, "Int" and "int" are both Maple commands, but work differently.
