I just created a forum, gradientdescent.co, that doesn’t have (and won’t have) ads or any form of monetization, and actually costs me a small amount of money to run. I would like to post a link to the site in my signature, but want to clarify whether this is okay since the site is non-commercial. I checked the rules and it says “competing sites” are not allowed in signatures, and the site is a forum, so I wanted clarification.
