OK - here's my $0.02.
I actually think it shows some respect for the forum when an old thread that answers a specific question is revisited or brought forward if the reader is asking for clarification or seeking new information - particularly if it is obvious they read and digested the original material, it shows they at least took the time to do a little research on the topic before asking the question. We always get the same questions over and over again as people join, not that I mind the questions or the new folks, just that I think they should learn to do a little digging first. I think it might have been last summer or the summer before, we kept getting the same questions as new people came in, I could almost cut and paste the responses from the "old guard", it became almost comical. I think many of our experience folks are just not responding quite so much to these this year.

I hate when silly threads are revisited, most humor goes stale - but that's just me.
