No, there shouldn't be a limit. When I first joined, the main thing that kept me around was the Life board; if that hadn't been there, I probably would've moved on.
I feel like a limit would just discourage new members from staying; how are they supposed to feel accepted if they're locked out of the two most social boards on the forum?
still think a minimal post count would be nice.
if you like animorphs, i'm pretty sure that 10 posts wouldn't be too much of a challenge to obtain.
i mean, you need 10 to read the books, don't you? people post for that reason alone.
as for the second part, we're not going to put up a big sign saying
'only high-posting members can view this thread', we could just make it a nice surprise when they've posted enough times (and have become an actual member).
i don't think we should be posting anything that's too personal for this forum, but i think we deserve some privacy from lurkers etc.
just my 2¢
edit:
i noticed in the member list, there were only about 3 pages of users with
0< posts <10 and 8 pages of users with 0 posts.
that's a lot of lurkers
