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.
I've only got one backup that I could find from 2006 that includes the StarChan character art imageboard and unfortunately it didn't have these images so I suspect that were uploaded after the backup was made. But by 2007 we'd closed the imageboards. So I went through my image folder looking for files with the right names and/or content based on the comments in the thread and I've manged to fix some of them. The first two I know are the correct images but the third one I'm a little unsure about.
