If anyone is familiar with futuba-style imageboards (the most popular north american one is 4chan, but there are many others), you'll no doubt be acquainted with the "sage" feature. Sage is something you can type into the email field when you post so that the thread is not bumped when you post in it.
I believe every slow-moving imageboard and forum should have this kind of "sage" feature, and this one is no exception. There's times when you want to say something but not bump the thread, particularly if it is dying or if what you want to say might start a flame war. It's a nice, convenient feature to have.
(Also, I posted this in another thread, but the irony is I had to make a new topic so that thread wouldn't keep getting bumped)
