treat Login/Signup as in desktop app
from #8864 (closed)
After picking riseup.net, I went to login to my profile. In the 'username' field I typed my username, but I was confused because in the desktop client, as soon as I type my username it auto-fills at the end of the username "@riseup.net"... so I thought I needed to type all that, so I did. I went back and re-did the process and found that I did not need to include the '@riseup.net'. It would be good to mimic the desktop client here.
