It started yesterday and runs through June 25th.
Anyway the point is to leave at least 5 comments a day on other blogs and to respond to at least one comment on your own blog. I love this idea because I really like to check out other blogs, and I'm sure this will lead me to some new favorites.
Plus reading all these blogs will keep me from overanalyzing my 2 week wait symptoms. I'm 11 DPO today and so far am not going too crazy. Hopefully NaComLeavMo will help me stay crazy free.
