Like Jon said use the same URL every time. I keep mine in My Favorites list so I get here or my place through the url's that work. As for the remember me not working if you have cookies blocked in the internet options that will keep it from placing the cookie on your system. Also if you run a cleaner like CCleaner, then the cookie gets wiped.
Most likely it's the url though.
As for the thank you for posting screen, getting rid of it is a mod. Look at the VB help forums for it.
