If you start a thread, Are you allowed to delete it, or is that soley a moderator function?

And now I have an answer.

"No." So now I know what happened to Zagnut's thread.

Correct. Only a moderator can delete entire threads. RCU would be a very confusing place if thread starters could delete a thread. Imagine a thread like the capiche or ucando threads where members contributed thousands of posts of information. Then at the whim of the thread starter he could blow them all away. Imagine seeing your 246 posts gone. This is why it is not prudent to allow members to delete threads. There is no reason to delete threads and if there is one good enough on the rare occasion a moderator can make the call as appropriate
