Okay, we'll try again. Tuesday at 6PM eastern. I don't know how much of this is necessary, but it might help to go to make some early preparations. Go to http://www.google.com/talk/ and click on Launch Google talk gadget. No need to download anything. A chat window should open. You may find that you already have some contacts. (There are people on my contact list I've never heard of. Possibly people you've emailed who have gmail will be on the list. Or not.) In any case try to add firstname.lastname@example.org to your list of contacts using the ADD button (possibly you don't need the ADD button. I seem to have trouble getting addresses in. Possibly putting the address in the provided box and hitting enter is the correct procedure. Fiddle around till it's in there.
You may already have a google account, as I believe you need one to have a blogger account. If you don't, it may turn out you need one, though I've seen nothing that specifically says so.
If you don't receive an invitation to the chat room by 6:05 PM eastern I will have no way of knowing whether this is because something's gone wrong, or because you forgot to be at your computer. So come to this post and comment that you didn't get invited or that you aren't able to accept the invitation for some reason.
Now, if you're planning to be here, send me the email address at which you want to receive the invitation so I can put you on my own contact list. I have Kiersten, Julie, Robin, Dave, Buffy and Meri on my list already.
