WoTC stands for Wizards of the Coast for those ignorant people out there.
Advantages:
1. You will most likely get any questions you have answered, with the swarm of people there.
Disadvantages:
1. Posts get buried the moment they are made.
2. No community; very few people with any personality. I know that the Werefrog speaks in third person and Cli\' Van Aquanova is a major merfolk fan, but... that\'s about it.
3. You are very, very likely to be ignored
4. Many people means many many stupid people
5. They are slow and unreliable
6. Sometimes when you post, it gives you a page not displayed thing, or nothing loads, and posts take so long to register, and the \"60 seconds between posts\" thing doesn\'t always work, so you will make double posts over and over until you learn to copy and paste, trust the system, and check back later.
7. I don\'t like them.
