Good job the "Remember me" function and the Firefox compatibility.
My modest suggestion would be to streamline the Autologin function a bit more, if possible, to something similar to e.g. Wikipedia, or PPRuNe itself.
That is, instead of an 'Autologin' button, separate from the 'Login' one, there could be just one button, 'Login', and the 'Remember me' tick-box.
If somebody logs in ticking the box, then the next time they visit the website and click on 'NOTAM', the whole login process (click on 'Existing users' and then log in) is skipped altogether, and the page with 'Route Brief', 'Narrow Route Brief' etc. appears.
Good to see that the website is developing anyway.
By the way, the link with the full details is broken (one 'http//' too many); the correct one is
this one.
Cheers
