No, not that I know of. Is there a limit I wonder?
Just an FYI ... I think it was about 2 years ago my AOL crashed for no reason. I was in the middle of doing research for a paper and my screen went dark blue and said all kinds of gibberish. After about 2 or 3 hours of playing around with the tech team at AOL I was able to get back on line, but I lost everything! Every email I saved and every favorite I had. That was a tough blow since I'm an education student and had tons of educational and kids sites bookmarked. If you REALLY want to keep a site, make sure you copy the address into word or something, just in case AOL has another foul up! I learned my lesson the hard way!
