In case you aren't subscribed to the SourceForge Blosxom Developer's list you probably aren't aware of a couple things...

There is strong movement towards getting the current working version of Blosxom up-to-date and ready with a set up "default" plugins. Basically this entails bug fixes, XHTML and Atom support and bits and bobs into the V2 code base. The plugin package would include a few highly useful and functional plugins that much of the community seems to use.

The second bit of news is a frank and open discussion on where to go next. Rael had tried and started on Blosxom V3 (you can download updates to V3 here) but the project fizzled. When Rael moved on to pursue other endeavours V3 was essentially dropped.

Now various developers are forming an idea of what they'd like to see in V4, which will ignore much of the ideas in V3 (let's pretend V3 didn't happen). The discussion has been going on for a bit, but if you want to hop in and contribute then peruse the dev archives. Then, if you think you've got some good ideas, join the list and get them out!

For a long time people have "lamented" that nothing seemed to be happening on the Blosxom front. Now it is, folks. Get in there and participate!
