VERY NSFW
I though that you should be aware of a very similar domain (VERY NSFW) “ttrpg.net”, which kinda sketchy. And by kinda sketchy, I mean is stuffed full of ads and porn. A basic check of registering a domain is checking similar domains and ensuring that you’re OK with potential visitors accidentally accessing the similar sites. It might be worth changing domain, if it’s not already too late.
TTRPG.net was actually a URL i considered when i was looking at domains. That said, at the time, it was basically a dead page (just one of those “this url is purchased!” type place holder pages), and the domain was listed for sale at like $400
