Why can't SourceForge just remember me?

I do not typically make complaints in my blog, so consider this a request for advice in good practices ;)

My problem is that I have to log in on SourceForge every day, even if I tick the 'Remember me' switch. I do understand that account log ins do need some time out… but less than a day? One cause of problems seems to be if I connect via a different network, but Cookies should not be affected by that? Am I doing something wrong here, or does SourceForge?

Are others having the same problems?
