I drew something lewd today and I posted it on e621. Does that make me an artist? If yes how can I add my username to the list of artists tags?

I fixed the artist tag for ya. If you need to fix a tag's type in the future, go to the 'Tags' section (at the top of the webpage), search the 'Name' of the tag you're looking for, and select 'Edit' next to the tag you want to fix.

You are the best. I will keep that in mind next time.

I love how there's threads like this, when there's literally PSA about this in pinned topics: forum #283267

Additionally thanks to new site, you can also change the type from wiki, so you can simply press ? next to tag instead of needing to search it from tags menu.
