Bumping old threads

Forgive the newbie question here but I have been browsing through the various forums and have come across a number of posts that I have something to contribute. Many of them at 4+ months old and I have noticed a few posts from people complaining about bumping an old thread. What is the ettiquette for posting on existing threads when it comes to time?

Do not post on a thread where the last post is over 30 days old. Thats the rule! Have fun!

Thanks Ivy and DED.

Too bad that SOME do not "get it".

i concur Rub. i was chastised as well for the "bumping rule". i did my best to try to look for the "rule" but was unsuccessful in finding the "proper etiquette" on this rule that seems to disturb so many. SO SORRY!!!!
