I just registered at doomspeak
I can edit my profile just fine.
I posted a test in the off topic
BB code is not turned on for users.
Since this is a very old version i can only go by where the permission is currently
In the control panel goto the permissions section
select groups
select the forum link to the far right of the line that has users
select Can post using Markup/UBBCode to expand the item
change the value to a 1 for each forum you wish them to use bb code
Save and exit.
Repeat for each user group needed
