Note: And, yes, this is an old thread, but there is a difference between "bumping" and "continuing" a thread. In my opinion, there's nothing wrong with wanting to continue an ongoing discussion, regardless of how old it is. As long as you're adding reasonable information to the thread, it should not be considered a "bump".
Sorry I had to bring that up, but I've been browsing thru this forum for the past two hours, and I saw numerous posts saying that it's wrong to bump a thread, when in fact, people were adding to the ongoing discussion.
