The forum.I'm down for just a place to socialize with a place for help if we need it. (i.e. "does this coastline look right to you?", "I can't get this unit to center", etc.)
As a practical example, there's currently a palette difficulty with the tech tree graphics I'm working on for the updated Lost Worlds scenario. King Arthur & I can probably sort it out (already got some ideas of what to troubleshoot). If not, posting questions here will help. Someone's likely to have dealt with exactly the same problem before, but who knows who the expert is until the images and files are public. And there's likely already posted answers in old threads here.... for serious discussions "how do I do this tricky thing for a mod?" I'd encourage staying on the forum.
Although I'm pretty Zoomed out after the past year, I'd still be interesting in putting a face to the usernames I've known over the years. With the caveat that I have been traveling a lot lately, and not on the forums much, so my participation should be a "great if it happens to work out, but don't bend over backwards trying to make it happen" type of thing.
