It appears this function is available in Threads - is there any way to do it in UBB?
From what I can tell - I can limit so only original posts are made (I do this in one forum) -but there appears no way to prevent replies from the general membership while allowing the thread starter to do so.. and I have a desire to (in just one of my forums) to stop all but the originator from replies.
Unfortunately, this isn't an option in UBB.classic. You would need to request a modification at UBBDev.com for that. Keep in mind that modifying your stock code will cause you to lose support from Infopop unless you restore stock scripts.
