I like that there are many options available! It also makes me excited when I get an email notification that someone has made some changes or done something new because then i know its going to be better than my last revision. 1.) There have been times where I would send out multiple revisions but at other times there were no emails sent back so sometimes i thought i had just done everything right, only to go through it all again just to find out nothing was changed. This software can really take some time if things aren't set up perfectly from step one. Make sure you do this before starting! 2.) Sometimes i wouldn't receive any notifications about what people did wrong even though they should have received them by default. I don't think there is anything i dislike as much as I love this program, but here are a few things: Don't give up if you make mistakes.
