Multiple homebrew threads?

[Tintenseher]

I've got a few homebrews I'd like critique on and help with, but I was wondering if it would be more acceptable to post several threads (one for each) or to post one thread and hide each in a spoiler tag. The latter seems like a better idea to me so I'm not flooding the forum. (Granted, I've only got three finished at the moment.)

Sheriff: If they're related, I'd say one thread. If they're completely unrelated, then either way is fine, if the number is three. If it's much more than that, try to consolidate them some.

Obviously, there isn't a hard and fast rule on this. Be respectful of the front page space and make your best judgment.
