GitHub is making development definitely much easier.

So the goal is to place all XOOPS modules there, old and new, so people can fork them, fix them, and hopefully contribute back to XOOPS.

Yesterday I've imported most of Wishcraft's modules from our SVN to GitHub:

Simon, I see that are still using our old SVN, but I've also seen that you have officially an account on GitHub, so now that all your modules are there, you might consider developing there

I also recommend to set up links to these excellent static analysis tools, as it will help you to catch some of the common errors. I use it a lot, and it's really helpful!
