The theme on my forum www.gsx1400owners.org/forum was written by our great departed friend Lesmond.

Since we lost him I've not done any theme changes and there are a few things which need to be fixed and also will need updating in future to maintain compatibility.

The theme is, I believe, not particularly complex in it's structure/coding.

I'm wondering if there's anyone who is willing to help me with this.

Cheers

If it's nothing to hard, I might be willing to try. However, I'm busy with TheCripZone themes and updating them for Jeff.
