I think this mod is perfect for a security improvement you can do in VB (inpired from
vbseo forum)
Set a temporary usergrup for registrations that has limited capabilities (just posting and reading, no bb code, file upload ... ) and make a promotion scheme to move users to default registered usergroup in vb with normal wrights after they have 10 messages (for example)
This way you prevent any spammer/ possible hacker to open doors in vb.
Is highly unprobable a hacker will have time to post 10 messages you will not delete so he can hack you.
