a few questions about the new site

[Troy711]

i wasnt sure where to post this, so this seemed like the best place to do it. so here goes:

how much space has been allowed for members to upload attachemtns each?

whats the 'public group' thingy mean in a persons profile?

and whats the 'number of referals' mean? and how does it work?

public group thingy means that your part of no special group.
your either normal, moderator, or admin.

as for referrals, on ct i know it had something to do with how many people you had gotten to sign up to the site, however I dont know how that'd work.
