Hi,
I have been using this program since 2006 and often in the course of customising it I see little improvements I could make, usually just HTML and other minor things.

I'm a developer of other open source projects like PS3 Media Server and Vanilla forums.

I'm not offering to be an active developer but if I had SVN commit access I could make infrequent contributions.
According to the Get Involved page this is the place to voice my interest so there it is

Sorry, but I think you can appreciate that SVN commit should be reserved to active particpants. But certainly that should not stop you from occasional contributions.

Simply create a ticket describing your changes and attach the appropriate files. We've found that patch files are not always so "universal" as they claim, so suggest you attach the changed module.

Please review the contributor guidelines. But most important, apply your changes to the source from the Development branch as that stream is where new features and improvements go.

OK, no problem.
