Where can I find a forum/discussion board for competitive programming? (ACM, TopCoder etc)

Question

Hello, I'm trying to prepare for the ACM competition in November, and I'm going through the practice problems and getting stuck on data structure or implementation problems. I tried to find a discussion board or forum for discussing these types of problems, but I couldn't find one in about thirty minutes of Web searching. Is there a forum for discussing ACM-type problems? I appreciate the help as I wouldn't like to spam SO when I need help with a problem.

Thanks, Kevin

The best place I found to train for ACM was http://train.usaco.org .

The ACM Archive seems particularly apt as well: http://acmicpc-live-archive.uva.es/nuevoportal/

I would also recommend:

Contest websites:

• http://www.topcoder.com (The topcoder forums might be specifically what you're looking for)
• http://www.codeforces.com

Online judge websites:

• http://www.spoj.pl/
• http://uva.onlinejudge.org/

Everyone knows about this by now, but it's still a nice resource:
