<font face="Arial" size="3">those of you that use PingPlotter might be interested in the new beta we've got up at http://www.pingplotter.com/beta.html. A lot of ISPs have been blockimg ICMP because of the people that have too much time on their hands, so they write worms and such like Blaster. We've got a new beta version up that uses UDP to get around this problem. Some of you also may want to check out our new product MultiPing. It's specifically tailored for online gamers, daytraders and other folks that need to only see the best endpoint (monitoring as opposed to diagnosing and troubleshooting a connection) so they know where to connect. You can find out all the details at http://www.multiping.com. As PingPlotter is, it's sold via the Shareware model, which means you can run it through the wringer and see if it's the right tool for you.</font>
