Looks like another one of our compatriots is biting the dust. I can't blame Ian, that's not a lot of revenue for all that work. I really thought it would be doing better than that. You need to know when to cut your losses. Being an add on product to a larger one is always a tough way to go as you're naturally limited by the main product and are always at risk of your key features being added to the main one.

Good luck in your next venture Ian. Hopefully you'll be able to put this experience to good use.
