A short time ago, Rejaw added a few new features.
The one I noticed immediately was 'Help' (and a help form) down at the bottom. I think a lot of the micro-blogging and lifestreaming services should be looking at that right now. There are new users every day and MANY have questions. Some simply get turned off on arrival.
In addition to the Help module, Rejaw has added user blocking (a necessity these days), a timeline feed, API additions, muting, and a host of improvements that will be of interest to developers.
The latest updates can be found here.
