Not that I know of. One of the mods could make one... but tbh there are relatively few active runners of this game so idk whether they'll think it's worth it. Personally I'd be happy to join it

There is likely already a server for Peggle players. Which might be better than a newly built server for a few runners.

This is the only one I could find. Consider using it if you'd like. I chatted with the owner and they'd be happy to have anyone join. https://discord.gg/587NrCf

I also have a general Popcap speedrunning discord you could also join if you want to i guess https://discord.gg/SuTK7t
