Ever wondered what possessed MSN to use yellow as a background color to be used when you make a new posting for the boards? I know a lot of people are not very keen on using the dreaded yellow.
I don't have the exact solution to this problem but I do have a suggestion on how you can do "rid" of the yellow. What I did on the beginning of this thread is simple. I just put a small speck of period on it, then hit send. I know you can still see it but it you really want you can click on the font size and make it a size 1 (the font I had for above was a 3).
That's just a suggestion, it looks better than putting something else like another letter or something. You can even use a smiley on the initial message if you want.
