you can't delete a thread,, if you want to delete your post on a thread find it on 'i'm on' and on your own post click report and ask for your own post to be deleted.
They won't always do that. I told a well-known family tale on a thread then thought better of it and asked for my post to be deleted but no.
I asked 4 or 5 times and explained why but no-one at GNHQ took any notice at all, no response and the post was still there.

which I like .
