It is very easy to make your first YEL, a (automatic) quest account is enough.
You don’t need passwords and email to YEL. The local session / storage remembers who you are. Give it a try
Guest accounts are limited to the device. But ok, who needs 3 smartphones?
If you are sometimes on your smartphone, and sometimes on another browser, then switch to Guest Account = NO. Enter Password and email. Et Voila.
Permanent Twitter integration (oAuth) is possible only with non guest accounts.
