Thanks for the feedback.
You're certainly welcome to review RightEdge and post on the forums on Elite Trader.
As developers of the software, we can't post there promoting it (it's against their guidelines).
There is already a 30 day trial. We think that's enough for most people to evaluate the software, and if not you can lease it for only $50 per month. So we don't really think the price is a barrier to people checking it out.
I think we'd need quite a large userbase to make it worthwhile for third parties to develop add-ons. Of course we plan to get there eventually.
The website hasn't changed significantly in a long time. We'd like to update/redo it, but right now given the choice between that and working on improving RightEdge, we're working on RightEdge.
