"My Threads" - Can they be deleted or refreshed?

Can the threads in "My Threads" be deleted or refreshed so that if you are a long term member you don't end up with pages and pages of "My Threads"? :)

Off Topic threads get deleted after awhile

Well, the whole purpose of "My Threads" was to list all the threads you've participated in and they will stay there unless the particular topic (usually from the Off-topic thread indeed) is deleted. MyThreads can be sorted by the latest reply or the newest topic, so it's easy to track.

Yeah.. I have like 20 pages of them lolol

OK, thank you. I can see how it would be easy to keep track, but wondered in the long term. Again thanks :)
