Why your site can't be always log in? I have to always enter my username, pw, I feel it is wasting time, you should learn other sites, keep login in for 1 day or forever.
I was also annoyed by this always keep get logged out due to inactivity but now I get used to it. They have like a unique url per account that is made when you created your account I thought that was the solution to this but the link they provide you doesn't work.
