Setting Up A Custom Avatar

[Auroch]

Type in the URL to your custom avatar. The URL must start with https:// and the avatar must end in .gif, .jpg or .png. URLs with spaces and certain characters will not work. For example: https://www.example.com/avatars/avatar.gif

Reminder: Animated avatars are not allowed.

This is misleading. Can this be added to?

I don't see how it is misleading; the .gif filetype supports animation, but is not necessarily animated. Static .gif files are perfectly acceptable (subject to all other avatar guidelines, of course).

I'm pretty sure they weren't saying anything about animated gifs, there.

The error message says "You did not enter the correct format for the Custom Avatar URL field. Please read the field description for the expected format." The field description does not include an actionable format specification for this error. It took me several Google/forum searches to determine that imgur is not "a website which allows image hotlinking for avatars". A list of the 2-5 most common image hosting sites which do not allow hotlinking for avatars would make this far more helpful.

[...], as well as the resulting error, are wrong. This is a bug.

The error message cannot be changed. This is not a bug.

Respectfully, that's really not how that works. If the error message can't be changed, this is an unfixable bug, but it's still a bug.
