My contributions are much the same as jcwolf's. I haven't been around very long...5-6 weeks. I don't know the file structures, modelling, or much anything else to do with serious modding of SH3.
I do love the game though, and saw the amazing quality of the many mods out there. I was totally amazed.
I do what I can. I help keep track of errors and write up information that goes into the GW FAQ. I also try to do small things that I know how to do, like turning down the volume of the cabin clock to various levels then bundling it in the correct format so people could load it quickly. It's not a big deal, anyone could do it if they took the time to edit and save some files and write a little note on how to apply the fix. But last time I checked it had been dl'ed 121 times. So it helped some people out there make the game even better, which is what everyone here wants to do.
I had the exact opposite impression of this forum than Werner1942 had. I thought it was very cool how so many people were doing cool projects and helping each other out.

If you wanna talk the talk, you better walk the walk. I expect to see your contribution soon.
