I have been a big fan of QuoteTracker even before the Ameritrade acquisition. There is limited support for crypto in the marketplace, and I'm very happy to discover through BitcoinTalk that you guys are taking this step forward.
Regarding email alerts, if users have a Gmail account (and for those who don't, they should get one), they can send email through their Gmail accounts with Google's SMTP servers for free. There is a lot of resources online to show people how this can be done. Like this one to enter Gmail SMTP info into any email app.
Simply adding these email configuration settings to Medvedtrader should be quick and easy.
