Remarks from BB:

That site maintains archive copies of contest problems. There are 2 different volumes of problems; Problem Set Volumes and Contest Volumes. The Problem Set volumes are problems from various regional (and perhaps world) contests. [I did actually recognize a few of them as Mid Atlantic contest problems.] The contest volumes are copies of problems of contests run by that site. [These can rely alot on "silly tricks", e.g., setting the time limit so low or setting the input so high that you can only do the problem if you know the trick the author was thinking of.] I pulled problems from both sets.

The site always you to register and submit your own solutions to problems for automatic judging. The judging isn't too bad (but presentation errors can be annoying...)

Occasionally the site runs contests and allows anyone from the world to join in. I've never joined one of these as the times were usually inconvenient (UVa is in Spain and the folks running the site are there).

Forum site for discussing problems from the archive. You do not need to be registered to read, but do need registration to post. Most of the problems [but not all] have a topic associated with them on the forum. You can find some extra test data here sometimes. (The better posts ask "what's the output for this input" and they get a response from someone who's gotten the problem accepted.)
