Yeah, bumping is the only way to keep people seeing your thread if you've mistyped everything in it, wrote it in a horribly unreadable format and generally fail at writing.
For everyone else, there's a new feature called 'Search'.

>implying anyone uses the search function on forums

Unless they're window shopping, yes, they should. It's how I found a couple of my cauldrons. It's how I find hats to lust over, and my favorite sellers threads.
You use it on sites like TF2OP, TF2TP, so why not forums (aside from the people that can't spell, format, etc when they post sales).
