ToME: the Tales of Maj'Eyal

Is there a place to request add-ons or give ideas or to support people who make good add-ons (like via their ko-fi page or similar?) Is this it?

I don't think anyone is taking commissions to work on add-ons since everyone who makes them is sorta doing it as a hobby or for themselves. You may be able to get more responses or a better idea on the discord add on channel.
