I have a play by post on a wiki game so time zone is not a problem. We also use Fantasy Grounds. I have it up 24/7 for people to log in and use to make skill checks, two or more people could log in and do roleplay independent of me being available. We are just starting people off, the other players are new to Traveller but are very good roleplayers. Can give you links etc if you are interested.
We had a no-show so there's an open slot on Friday night, European timezone. DM me on Discord if you are interested in joining. Here is the notice on Discord, where there are also other games advertised: Deepnight Legacy: discord link
