I think what Beat was saying is that the Joomlapolis "Forum Settings" tab is a standard CB tab with standard CB Fields.
Took a peek through the SB plugin and it does not appear to have any code for an edit tab...
So it looks like simpleboard just knows what to look for in the profile (unless there is a SB hack...)
Anyway...
Looks like here is the field names used (from reading the html of the Joomlapolis Forum Settings)
View type = sbviewtype
Message Ordering = sbordering
Signature = sbsignature
may or may not be right but you can give it a try...
add a tab from the admin side
Then add those fields above to it
NOTE: I have not done this as I don't use SB... but this should work... if nothing else it is a good start
Hope this helps,
Greg
