Well.... I see good and bad about the options:
1) Moving threads to a different section means people would have to search in a different board for answers. This would also reduce the thread count in that board, which actually means something to people that are looking for help. Plus, moving the thread would stop people from using the solved feature since they'd have to go searching if they later realized the thread wasn't solved.
2) Increasing the page count might help, but would also increase loading times/traffic per page. Although the increase would nearly be negligable and I think we should probably consider this idea.
I have no problem with people bumping a valid post after it leaves the first page with no responses. You're free to do it. Also, if you're not getting responses, it's possible that no one knows how to answer the question.
Keep in mind we have boards that are more specific (OOP, App Design, Databases, etc).
