Hallafreakinluya!
I know some new folks find threads that they want to be a part of; I have even done this myself in the past. But it is very annoying to see old threads bumping new ones. Especially when the old threads have become really old news for older members.
I think if you see an old thread and you MUST join in you start a new one and link it to the old one.
But it would be better if you try to start new and original threads so we are always learning and contributing.
