I have... I keep forgetting to update the calendar... must get back on that. I liked that I could share the calender with hubby and he would put things on that would affect me and kiddo at home... and then have a summary for each week went to us. I also have used the shopping list, but since getting the smartphone, I just use an app on that or email hubby if he is stopping... right now the most I use is the journaling part. If there is something I want to remember to scrap, I put it in the journal, which hubby can see, too... oh, and I guess I use the todo lists to keep track of things I want to make for kiddo's schooling, scrap pages, etc...
Hmm... I guess I used it more than I thought, I should revisit that... haha. I know the only think that annoyed me is that it doesn't remember me and I have to log in every time I go to their site...
