When the old BSF forum was active there was a Show us what you are working on thread in the Morrowind Mods forum.
Note, why threads over at BSF are numbered has to do with Bethesda's post limit of 200 posts for threads just to prevent the server from being slow.
I also know that the Mod Author's forum on Nexus also have a "What are you modding right now" thread or similiar there people can share their creations or give feedback to other modders.
I begin to mention that I've been working on a startpos mod for BI for the last 5 years or so now and then, so now I return to work on it after I had to reinstall RTW in Steam recently.
It's playable, but I want to add more stuff just to make it more polished.
