Can non moderators delete their own posts?
I cant seem to delete my own posts when logged in as one of my member groups.
Is this normal or is there a member preference of sorts that i need to tweak?
It is not possible, sorry. You have to tweak/create custom code/addon for it.
All possible permissions per forums/boards are handled via Forum Module CP :( There is just can edit, and that's what my members has done, editing entries to have only a dot or few.
And if Im wrong for some very odd reason, It would be nice to know where that magic setting might be.
