I wonder why I cant seem to login anymore , everytime I do , kill my self writing the longest reply in the world , push the post button and it says that there is some bad link something something ..
The easiest and first thing to check is whether the "Remember me" box is checked when you log in. If it is not checked, your connection will soon be lost.
It happens to me sometimes when I log in from public computers or even (hush hush) work computers.
