I didn't say there were plenty of folks contributing - I said there are plenty who might like to. The gating factor was, and is, time for the gatekeepers to do their thing.
In the short term we can get around this by just making tarballs available. In the medium term we might let people upload patches which would be available on an as-is, un-reviewed basis. Ultimately we'd want to have the same sort of process as we have here at OpenACS, where patches are looked at before being accepted. But we haven't got the manpower to make that happen right now.
