Yes there was a letter read to the congregations about web communities and personal info on the internet.
The letter was targeted at sites like myspace.com but there was no mention of any specific website. This is a definite shift from recent assembly and convention talks that have demonised myspace, but without specifying why such sites are dangerous.
The letter was very detailed about the dangers of child predators and had the substance of the TV Dateline "To Catch a Predator" shows. It even warned of mobile phone web access.
I have to admit this was a balanced and informative letter without the haranging and paranoia of the earier "NO MYSPACE!" rants. There was little mention of apostate issues, the letter was focused on sexual predators and the dangers of having personal info for all to see on the web.
