Cool! I'm planning to make this a semi-regular thing as my circumstances allow and I plan to run the server at different times to cover different days of the week and different time zones. This first time is gonna be trial run to iron out any bugs and to generate a bit of interest. I'm gonna be hanging out and playing the game until someone who wants to chat joins so there's no pressure.

its funnn!!!

Wednesday seems good, depending on how many spoons I can muster on the day.
If you're keen then we can arrange a time that suits you better than this time slot I picked - I reckon you and I are in similar time zones.

A very good question. I've just checked and it's possible to view other players' Steam profile page, as it would be with any other online co-op game. This isn't the same as your Steam ID though, it's just the public-facing info you have on your profile page. I actually haven't even set up my steam account in all the years I've had it but I know that other people have set their profile to private or public and this is all I someone else is able to view of a private Steam account page:

So it's profile pic and username, nothing more than that and both of which can be edited. I opened the options menu and I think I can request to follow or friend the private profile but that's it. I really appreciate you asking this - I'm going to edit the post with updated information based on your question.
