I created my account back in 2017, was being truthful to my real age, and now my account is stuff as a teen account when I'm 21. I was 17 when I made the account and now it's been 4 years but I have no access to any mature or adult content on second life. I would like to be able to change this so that I can go to land that has body meshes and clothing and whatnot so that I can update my avatar but I have no option to change from "general" to any other rating. Is my account stuck as a "teen" account forever? Do I have to change something in my setting to show that I'm no longer a teen? It's starting to get really annoying and I'm about to just sign off and not sign in again, especially if I have to make a new account just for that.
