How to make old discussion into one hot and lively one topic?

If you have a thread that you want to come back up for discussion, go in, pick a response, and comment on that response. That brings it into recent or current discussions. If someone else sees it that didn't see it before, then all the better. If you are really determined that a discussion needs to be seen, do that several times. I had a friend who went back to all of my old discussions from when I was a new user. She is a new friend and she responded to several of them, then others saw them, and I had to go in and rate lots of new responses to my old discussions, what a nice surprise!

i just want to make clarifications in your questions. when you ask of 'reviving old discussions' you mean your own discussions or discussions posted by another member? if you mean your old discussion, you can have it go back to the 'hot topics' or 'today's discussion' sections by adding comments to one of the responses made by others. if you mean old discussion posted by another members, well just go over the discussion and respond to it with your thoughts and ideas. if you mean to revive an old discussion in another perspective, i think mylot would still allow it as long as your contents are not exactly the same as the old one. mylot prohibits copied/plagiarized discussions.

I think it would be possible if you can come at it from a different angle. But even if it's the same topic, providing that it is written in your own words, I am sure there would be plenty of users who find it who didn't respond to the first one, mabye.. :-)
