Let me explain. No, is too much; let me sum up:
1. The secret ingredient will come from Core plus Complete, at least for the first several competitions.
2. Any 3.5 book can be used in creating builds.
3. I'd strongly prefer to avoid Dragon, since access is much more limited.
4. Likewise, I'd prefer to avoid 3.0 books with no official 3.5 update.
5. While I'm a big fan of UA, again, I'd prefer to avoid it because of the mutually-contradictory nature of some of the variant rules presented within. It just tends to lead to too many questionable situations, like folks trying to combine Generic Spellcaster with normal base classes.
6. Note that I'm not saying "Absolutely no" for any of the above. If there's a really, really good reason for bringing them in, I'm willing to listen--it's just my opinion that they're going to muddy the waters more than they're generally worth.
7. 25 PB for stats
8. I hadn't thought about it, but banning Leadership is probably a good idea just for logistical reasons...unless, of course, we're doing "Battle Leadership."
9. For this one, let's try mailing the entries to me, and I'll post them. If that winds up being a horrible mess, we can do it differently next time.
