Brainstorming!!
what can you say about the proposal of migrating to a new server and elegant forum software at the same time.

Introducing:
SMF "Simple Machines Forum".
Simple Machines Forum (abbreviated as SMF) is a freeware Internet forum application. The software is written in PHP and uses a MySQL database backend, although multi-database support is being developed for version 2.0. SMF is developed by the Simple Machines development team.

Forumotion has its limitation while SMF you can modify anything at your own view..

I can help you with the development in the said proposal. Also, I do have the background in PHP (Hypertext-Preprocessor) "Apache or Nginx web based servers" and mySQL as a backend database.

Any Questions?
