Yah00 is known for its expliots.There are codes you can insert in filter #1 that help stop some of the problems in Yah00.But my advice is to use the JAvA version of Yah00.Les "boots" and less problems with Yah00's known script kiddies.Which is a major problem with Yah00 chat.Yah00 really needs a major patching done to it. And I do not use the yah00 instant message software.I chat in yah00 dailly in hackers lounge #1.Few script kiddes come there,when they do they usually are running "booters" So useing the java version is better.
