come on, one post per minute sucks. I would not visit this site anymore :(
I am pretty confident it will stop very soon, if not we will have to make login mandatory...which would be very sad for the internet and humanity. Again few idiots would destroy something many good people worked on.
i already told a solution to this: with an account, it is permanently checked, so no problem.
as guest, you have to check it. if you're a 3-post-guest, it won't annoy to check the box "everytime". if you make more than 5 posts, you're better off with an account anyway. (most ppl actually create an account without the need)
