Are you getting a lot of the "Page Not Found" messages when you try to post or come to your groups? This is a common MSN glitch type thing that happens in groups that is caused when MSN works on their servers. (They call is server maintenance.)
Try hitting refresh when you are posting. You can right click and hit refresh or you can hit your F5 key on your keyboard.
One thing I like to do before I hit "send message" is to copy what I've typed just in case its lost. Then I don't have to re-type everything into a new response box. It sure saves time and frustration.
So, Wallers, don't give up, hit refresh!
