Don't know if one exists here, this is the closest thing I could find:

It would be nice to have for my forum where once a new member registers he is directed to a designated welcome forum for registered members only where he can post a "hello" message and see who else is there.
Right now I'm doing it via the PM option, and may need to continue doing it this way unless somebody here is kind enough to point to where such a mod already exists if they've seen something like this before.
TIA
