Well if you guys are in discord you can come and join and chat in here
https://discord.gg/JjuRJPn I don't know about telegram all too much but you can find people interested in projects and some miners on there.
I recall joining this channel the last time there was interest in reviving Prototanium, but you were uninterested in funding the development of the project. If you have miners available in that chan then they are welcome to try and restart the Pr chain from the Github linked above. But as it stands now, I will be resetting testnet3 with the next release of UNO and cut off the dead weight.
