I don't understand why the spam issue has not been resolved yet.  A ton of spam this morning!

Here's some more help. 

Any title or question of a post containing http:// should be automatically deleted. 

Clearly there is a name generator in place somewhere creating new accounts.  Is there not some kind of higher security name creation account done here at mapleprimes?  Ironically you would think this being a math type forum it would be hard to spam.

Anyone interested in modifying and expanding the Maple FIFA simulation for the Eurocup to include the knockout round?  Any interest?

Maple 2016.1a now available, fixes issues reported here http://www.mapleprimes.com/questions/211561-Why-Does-Maple-20161-Improperly-Treat-X2

Thank you Maplesoft for your quick response to this issue.

Just a simple little proc that grabs and displays some simple data for general stars (I've only listed a couple for starters).  It wasn't till later that I realized it's not an up to date database as it doesn't contain more recent interesting stars like Kepler 452.  One would have to go to the SIMBAD astronomical database for which I have not yet devoted any time for .. at least not yet. 

StarData := proc (a::string) local b, c, d, e1, e2, e3; b := StringTools:-DeleteSpace(StringTools:-Substitute(a, " ", "+")); c := HTTP:-Get(cat("http://www.stellar-database.com/Scripts/search_star.exe?Name=", b)); d := convert(c[2], string); e1 := d[StringTools:-Search("<H1>", d)+4 .. StringTools:-Search("</H1>", d)-1]; e2 := d[StringTools:-Search("Right", d) .. StringTools:-Search("Standard error in distance", d)-8]; e3 := StringTools:-SubstituteAll(StringTools:-SubstituteAll(StringTools:-SubstituteAll(e2, "<BR>", ""), "<B>", ""), "</B>", ""); print(e1); print(e3) end proc:

Most of the tags in this question example are rediculous "the, you, is, and, help, how," etc... .  I tried editing them but I cannot save tags to remove junk tags.  Above all, the most important tag to the question Poincare is not there.  This specific issue is for the recent question  http://mapleprimes.com/questions/207460-Poincare-Section
