Steve Noonan updated his site with all sorts of stuff, including word of a new SP Doom add-on utilising the Gothic DM texture set. He could also use some feedback to his UltraFE front-end, supporting every known / future Doom add-on / TC / port. Go give it a looksie!
The Deimos Incident project is apparantly still going strong. The site has a large update but unfortunately I can't reach its URL. However, you probably can so check this one out.
The Last Day On Earth site has been updated with a progress chart. It looks like they're close to releasing the first episode of this project.
