stop bothering people about payments right from the beginning!
It's not even a ready product yet and I only signed in because it was supposed to be completely FREE. Give people real free access for at least several months while the program is still in Beta stage (because it's still so far from perfection...) and you'll have everything done by the people themselves - tons of words, translations and examples added. And really? Blocked options, pop-ups asking to "go pro" AND trying to force people to download a toolbar? Guys, you really can't be serious about it. Totally NOT recommending.
