Yes, currently only I can create channels. If you want a new one, you can propose it in #CEXED56UR and we'll discuss it

It makes sense to only have channels for topics of much common interest or relevance, otherwise there's be too many for every topic. I personally see a lot of potential to explore, but as yet it's just me :) I'll dump some of my thoughts / shares, and maybe we'll see if it ever becomes a topic of common interest or relevance
