OOO OOO OOO, my first hack! I'm so 'cited...
Since the forum I was interested in was a Classifieds section for my users, I wanted them to have the ability to close the topic and have it marked as "Sold".
I hacked ubb_topic_maint.cgi and added the following code;
[code][/code]Within the sub, at the point where you check for admin/mod status, I added a check to see which forum I was in. If it was not the Classifieds forum, I ran the routine. It seems to work OK and has not had any affect on the security in other forums. It only allows the user to click the "Close" button at the bottom of the topic, not the "Delete" button; however, the topic owner can still edit and delete.
