I like that it's easy for parents/teachers to see what is going in school with their child without having to log into each individual site separately! It can be difficult at times when there are multiple people logged onto one computer trying to do different things (ie; logging grades). When you're looking through your class roster from within xPlor, if someone else has already been assigned an "assigned" status by another parent but hasn't yet updated his/her profile info - sometimes this doesn't show up until later in the day since we have so many students who get sent home early due to illness etc. Sometimes teachers will assign them as well even though they haven't actually signed-in. This isn't always possible unless you send out emails asking everyone whether anyone wants to accept assignment which takes time. If any of those kids were previously unaccepted assignments then these would not appear under other users' profiles either. Also, some schools just don't.
