I've got text based flair working! It's not automatic, so if you'd like some user flair please reply here with the following:
- Flair Text (Please keep this relatively short)
- Background color
- Border color
The default border/background color is what you currently see in my flair. There is a 50k character limit in the CSS, so to cut down on characters it's preferable to use the default.
If you want to get fancy, provide a hex value for your desired color. Otherwise I'll go with web-safe color values.
In the future I'm going to look into getting image-based user flair set up.
