Anyone know why every time I change my profile I have to log back in? It's a PITA!

No idea and doubt it's ever been raised before. How often do you change your profile for it to be considered a PITA?

Why do you need to keep changing it, mines been the same for 8 months

'cos I'm wierd!

I update the signature now and then, it's not really a big issue, I'm just more curious as to why it does that's all.
