I think it is a great idea: You could have themed boards:
1. Strongman (as already mentioned)
2. NFL
3. Pro Wrestling
4. Time management (for working out around a busy schedule)
5. Alternative medicine
6. Dealing with specific ailments (cancer, GERD, etc, etc)
7. More bodybuilding stuff
Each plat would be the mod and if it got out of control, then the board would go bu-bye…Some of the topics above seem blah but the trick is to have boards that appeal to everyone (to bring in more members)..And even if there isn’t that many posts on a plat member’s board, at least people will still be able to see the info that has been posted about the subject (good for the archives) and the mods (the plats themselves) will not have to be on 24 hours a day to monitor.
