Sorry about not responding sooner. I'm going to pull the old newborn excuse. everybody is doing well, but no one is getting much sleep or keeping up with mailing lists.
log4net had a reasonably successful reboot a few months ago. There is a bit of a chicken and egg issue with ASF development is that granting commit rights requires a history of contributions to the project, but it is hard to establish that history on a project that not in an active development phase. In the log4net reboot, an established ASF member and motivated user of log4net (but not an previously active log4net committer) acted as a SVN clerk and mentor to motivated users without an established history to pushed through the first official non-incubating release of log4net. The problematic issue with forking to GitHub is that it can become extraordinarily difficult to migrate that code back to the ASF since the ASF has very high standards to make sure that all code can be traced back to the original author and that there is a clear record of their intention to donate the code to the ASF. I'll write more this weekend.
