At present, URL custom profile fields are limited to 50 characters, which makes it impossible to enter many valid URLs.

Instead, the character limit should be increased to the maximum possible URL length (as determined by standards for URLs).

To make your PR easy to review, please post the reference where you looked up the URL length limit.

One of the biggest things that will make it harder for new users coming for reddit is to find Lemmy's website itself.

botui.message.add({
