I've made topics that are no longer getting viewed or responded to, and I want to delete them. Is it possible?
There's no real way for you to delete them, but what you can do is message or tag one of the forum moderators and ask them to lock and unlist your topics.
I think you have to use the little "..." emblem to flag them, and one of the options should give you the ability to write a note requesting that it be deleted.
Funny thing... I still get the occasional Like & Retweet of tweets I posted 2, 3 or more years ago. You never know.
