Signup and Profile Questions...(help)

[onehost]

(1) Where can I edit the pre-sign TOS agreement? the tos
that a member has to check before he can actually signup....
where can i find it, and or how do I edit?

(2) I would like to limit profile usage for new members so
to prevent drop in links, or link spamming...How can i set
this up so new members can not access profile until x
number of posts?

Thank-You
