I use Flarum in conjunction with another Laravel site, creating users on the fly as needed in Flarum. I set the avatar_url directly in the Flarum database when I make the user.
Yesterday I noticed an issue because a user's Google Account avatar URL was longer than the 100 characters allotted for that field in Flarum.
I modified the Flarum users table, changing avatar_url from varchar(100) to varchar(255).
That sounds like a harmless change, but I wanted to see if anyone sees an issue with it.
