So I want to change my username, but how can I search to see if various names I want are available since the search function is still down?

U can use ur profile link. If the name is available u will land back on ur own profile. Example: This is the link to my profile: https://subeta.net/users/Emrah (here u will see my profile) And this is the link to the profile of "emrahemrah" (which don't exist) https://subeta.net/users/Emrahemrah (here u will see ur own profile)

gotcha, thanks!
