Issue:Flexible input on opt-in

Priority 3 Created 2023-02-09

It would be friendlier if it allowed or even made it clear it asked
for usernames without the leading @. It’s still unambiguous, right?
In the "add me to the index" would be good if the search box could parse an http formatted account (https://instance.com/@user) as well as the standard @user@instance.com shouldn't be too hard to parse the server URL and account name from that format :)
The contrast meant I missed it when copying from my profile url - you could also just make sure failed attempts are logged and evaluate how many users screw it up like I did :D
