Everyone on here has these cool and beautiful signatures

I usually go to account and then preferences and the signature to update it. However, when I do this, weird crap happens. Like, (for me) it doesn't save. I tried to create a ticker and when I went back into the board to view it, it wasn't there, it was just showing the code. I tried to center the text of my history and that won't save either. I also tried to include the link to my chart and it looked fugly (although I think it worked).
Does anyone have any pointers?
I've always considered myself fairly computer savvy. The Bump has me stumped.
