Similar to Tweetdeck, Hootsuite is a social media management dashboard. It allows to you to manage more than one account, schedule tweets and messages and analyze social media traffic.
I love it!! I like that parents and students can be alerted and no personal info is exchanged. Seems very easy to set up and use. Do you have experience using Remind101?
Yes I do, my parents love it. I used to do more with a class website, but never had anyone read it. I figured, everyone now a days has cellphones I'd just send them messages that way. It's all anonymous so my personal info is safe. I just send quick messages about what's due or coming up.
