Paul, I’m on my Ipad and I stay logged in. I even used our old friend Google to find the Crossword Solver site and went into the site that way but I was still logged in, I presume my IP is being recognised.
I can’t see that it matters, you’ve got to be a member of the Forum to be able to log in.
IMHO it makes life a lot simpler but are we are missing something important regarding security?
