Hi angelv,
No, there's no corner of SPOJ like that.
What's this other place you hang around?
The haskell wiki has a few tips for getting started on SPOJ:
haskell.org/haskellwiki/SPOJ
And if you have a specific question you could mail the haskell-cafe mailing list, they are usually very helpful.
You can occasionally see code posted in the forums. But its invariably buggy code with the author asking "Help me, someone please debug my program for me". They often receive help and are then very quick to remove their code from the forum, in case it benefits anyone else. I've often thought this is a very strange practice.
