Review my classroom web tool, Eduset
sachinag: While I applaud your initiative, I cannot believe that teachers would feel comfortable using something made by a single person who just graduated/will graduate? high school this year.  You can keep your name, but I'd recommend taking out your relative youth.Also, I'm always a big fan of competitive analysis charts, especially if you're competing on price.  Here's ours: http://www.dawdle.com/selling/index.php/fees/  I will say that I'm with Brad and $4.99 a month feels like you're selling yourself short, but that is $60/year.  Perhaps make a couple more tiers right off the bat to try to nudge people higher?Lastly, I wouldn't say "if your students can use Facebook, they can use this" with a screenshot of Gmail.  That shows a lack of attention to detail.
