A post that does not have a reply has the topic in bold type. This makes it very easy for those of us looking to help.
You may think that because your post has fallen off the front page that it is destined to be ignored forevermore - this is not the case. I and others regularly trawl back to find posts that for whatever reason have not been answered, and having the bold topic title means we can find your post easier. A bold title helps us to help you.
But if you just bump it, you are removing the best way of getting help aren't you ?
If you are going to bump it, then at the very least add more information - maybe the first post went unanswered because there wasn't enough ?
If your problem is urgent, then use IRC:
And do NOT start additional threads.
