I know some feel 'bumping' isn't as important as newer threads, and then there's the other side of the issue, where there are those that enjoy reading an older thread since many times newer members would never notice the 'older' thread unless one of us bumps it. In that case they enjoy it almost like it's a 'new' thread to them and we get new replies.
To 'bump or not to bump' guess there will always be two sides to how people feel about it.
Personally I love getting some of the old threads stirred up and brought back to the top. I've even found threads that I don't remember or may have missed the first time around or even found that a year later I have a different idea to add.
But I agree that 'bumping' in moderation is the best way to go.
Thanks so much for your input.
