I've run Mongoose Trav on Rpol.net. It lasted a couple years and was lots of fun. Died out due to the usual PbP delay/malaise. I stayed on Rpol, as opposed to here, as it was dedicated to gaming with an integral dice roller, image support etc. In addition, you could create your knowledge base and Library data and store it all in one place.
Never really considered running one here. No offense, but the COTI crowd was not very welcoming back then (2008-11) to Mongoose fans. I figured the PbP games here were allowed to long-term contributors.
However, since my PbP games have evolved to include Roll20 maps and Obsidian Portal for wiki/information, I may be open to running something here. I've been out of the PbP thing since my separation/divorce. My job is time-consuming though so it wouldn't be daily posts. I committed to e/o day.
That being said, I advertised here awhile back and didn't a ton of interest so if that's changed then I would consider running something with some caveats.
Main caveat... I changed my go-to system for Traveller to Silhouette although chargen is all Traveller just hacked. Character Generation would be completely recognizable with some additional skills, Life Events but basic mechanics are (Skill determines # of d6 rolled, attribute modifiers affect total roll).
Long Story, Short Conclusion
If folks are interested in what I'd like to run, I'll do it. Specifically, it's Traveller using Silhouette. I'm currently running no PbP games and only a tabletop fantasy game.
You can see an example of Silhouette/Traveller here..

Here are links to my original proposals:
Hard Times
There are some issues with converting trade/mercantile stuff and much of the map being unavailable. But I definitely am still interested in it.
Or the Rebellion Era, running some published stuff or new ideas.

Gateway To Destiny/Glimmerdrift
My all-time favorite era for Trav.

I would add that I've been working on an ATU which is reminiscent of the New New Era (1248) but a bit less smashed.
In addition, I did a short hack for the Clement Sector also. Same Silhouette system. But the Clement Sector is a bit tame so we'd either have to have serious self-starters or change the setting quite a bit (open up below the Darkness).
Trav 149
This is the other idea I've been currently working on. If you don't like Trav 1248, you won't like this.

Tl; dr
If you don't mind using Silhouette (skill determines # of d6 rolled, attribute is a +/- modifier that matches MT Trav), I'm willing to run something. I would likely use Obsidian Portal for wiki/rules/images, Roll20 for battle maps (if needed) and the forum here for everything else.
Let me know.
