Allowing Users to Add themselves to a different user group

Hello everyone,

I have a safe-for-work (SFW) forum and a not-safe-for-work (NSFW) forum. I want my users in the SFW forum to be able to add themselves to the NSFW forum if they choose (ie, pressing a button on the forum somewhere that adds them to the NSFW user group).

How would I do this?


Nice! Might try that out... Then I wouldn't have to manually make certain people "Model Access" on my site, just tell them to join that user group if they'd like to be able to have "Model Access" lol. Anything to make my job easier and theirs as well lmao
