I know I sound like a broken record, but for those that want to actively do something to see CoH live again, join in on the SEGs project. Test, code, or just monitor their progress. Considering this is an open source, volunteer movement, they have made tremendous progress. Their Discord channel is where most of the real-time dialog happens, but if you download the Issue 0 client, and help test functionality, and post issues on their Github, it will help them achieve their goal (and ours) of having a playable form of CoH sooner, than later. It has been a quite satisfying experience for me so far.
They are interested in getting as many of the faithful involved as possible, to help in these things, so jump in! Have a hand in making the dream live again!
Hopefully, the mods don't have an issue with my droning on about SEGs in this space. :-)
