Signature on Registration..
 

i was looking through my site and i can't seem to notice an option to have the sig box on like the older vbulletin

how would i add one so all my members are required to have one ??

While it would require a bit of modification to make the signature be required, you could add a custom profile field as a "second signature" and make that required.
Then, add $post[fieldX] to the postbit template, exchanging the X for the postbitfieldID.

well i was thinking about that the other day could i add a textarea then make it add whats in that content into the database in the signaure field ??

Hmmm... that would be an option.

The easiest would probably be to make a cron job to update the signature field once an hour with the value in the profile field...
