Hmm, thanks. We'll have to work on the front page copy.
Do her students never reply to the text messages she sends out? That's the core of the value-add -- whether inside or outside of class, students can reply to ClassPager and we show it to the teacher on the web site.
If she doesn't want students to be able to reply at all (i.e. she wants it to be totally 1-way communication) then I'm actually inclined to agree -- Remind101 is definitely the best and most cost-effective choice there.
