First of all, thank you. We appreciate any feedback, positive or not.

The fact is that the FBML technology is almost dead and there is not our fault. The ⌠FacebookTab■ module stays live till the FBML-engine is disabled by Facebook engineers. However you still the owner of lifetime license of FacebookTab FBML version and can use it until Facebook-team stops the FBML working. It like if all hosting companies stop using PHP and start using other cgi script.

f-Commerce go - is totally new module and technology. And we are in our right to do new purchases for it. However we think of our existing users and try to find the best offer for exchange for new module.
⌠f-Commerce Go■ provides more features than the ⌠FacebookTab■, it has entirely new engine and another philosophy. The part of it is a hosted solution so we have to spend time and resources to support it, that is why the ⌠Silver■ f-Commerce plan costs a fee.
The on-time paynig licenses for such service is unprofitable.
However we decided to give a discount to existing ⌠FacebookTab■ owners. We think It▓s a good deal.

Also there is the free ⌠Basic■ plan. It is simple and doesn▓t require much resources.
