I decided to take this Writely business into my own hands.
I Googled writely invitation/s and left my name a few places. The one that worked was Jerry Wang. Thanks, Jerry. You are awesome!
I like it pretty well so far. Still fooling around. This is only my second document and my first attempt to post to me weblog herein.
So now I have Writely invites. Need/want one?
[update: couldn't get it to publish to my weblog yet. But that might be temporary.]
