apparently, you can join Dreamwidth this week, without an invite code. the week runs through tomorrow, but i just found out about it today, so i'm passing it along.
i've got a copy of this blog on there, at username faceless_wonder. if you're on there, or end up joining, let me know. the best way for me to describe DW is that it's like Livejournal without the spam. i'm an old luddite who loves her Livejournal...but it's really nice to not get spammed incessantly. sadly, LJ has become a cesspool of spam comments in the past year, so much so that i cancelled my paid account there.
my one complaint about Dreamwidth is that the communities aren't as numerous or active as they are on LJ, but having more people migrate there should fix that, right? ;-)
