Hey Kimberly
I have problems getting in sometimes because the server that YorkieTalk uses for the chat is down or what have you.
If you're interested, another foolproof way to get in is to go to:
http://www.jpilot.com/chat.html
-then change the nick name to your own (like Kimberly55 or something)
-change the server from the dropdown menu to "irc.prison.net" (it's one of two choices)
-then click the green arrow at the bottom. the chat will start
-after it starts, in the little white bar where you usually type, put this:
/join #yorkietalk
and there you are.
