Case sensitivity for usernames
According to the Matrix client-server spec, it's OK if some user thinks his username is @TheCoolDude:example.com
.
The server is supposed to convert a mixed-case username to all lowercase before performing any real operations with it, like doing anything with a database or comparing to another username etc.
Circles Android is having problems when the user signs up with a mixed case username. We need to verify that Swiclops is handling this correctly -- sounds like we are not.
