If you were supposed to get an email from the forum but didn't (e.g. to verify your account for registration), email Wes at stararmy@gmail.com or talk to me on Discord for help. Sometimes the server hits our limit of emails we can send per hour.
Most of the other established artists also have pages...you'll just have to dig in the wiki to find 'em.
We don't use Starchan anymore, though. If we need an image, we either use an outside source or, if it's an image for our wiki pages, upload it onto the wiki itself.
