Ok, i'm new here (obvious after seeing my post count), and I like what you've got going on here.
I have a suggestion regarding tutorials; I think the admins (or even the community at large) should compile a list of tutorials they'd like to have for each language. Since all the languages listed in tutorials are imperative, the list could apply to almost all the languages. Something like:
-Dealing with Strings
-Dealing with lists/arrays
-Functions
-Classes
etc.
I'd be happy to write tutorials for the languages I know, i'd just like somebody to tell me what they want the tutorial(s) to cover
anyway, just a suggestion, carry on...
