So I recently signed up for Stack Overflow and wanted to write my first question.
Then, after carefully wording it and writing the post (it took.. I don't know, 20 minutes), I click on "log in" (as in: before posting it said: either login or fill out this form, and since I already have an account I click "login". However, I assume it asked me for the login because I switched to the http://security.stackexchange.com section instead of Stack Overflow when I registered, maybe you should combine the login for all?). Then it successfully logs in, however my post I just wrote is lost.
Clicking on the back button doesn't bring my long post into existence either. It has vanished.
