Hi there! It has been 10 solid years since I was last active here, and my interests on my profile have changed significantly. However, I can't seem to figure out how to edit the Interests section. When I go into Edit Profile and click the edit button on the Interests section, all it lets me change is the name of the section. I've been looking around in other places like the Preferences section of the site, but I haven't figured it out yet. If anyone can let me know how to edit my Interests section, I would be super grateful. Thanks in advance!

You can no longer edit those. There used to be an old link you could still get to for years, but it no longer works. You can add your own interests via a blank block (as you have), otherwise just delete the old block.

If you want to see the link for yourself (its just a blank page now): https://subeta.net/preferences.php?act=interests
