If we don't hear anything by next week, I'd be worried. If they're close to having the S1 filed, then I am sure they have more important things to do than address the same questions I have had for a year.
I know we give them the benefit of the doubt a lot...but in a way, I believe they have earned it. You have to remember that certain things are beyond their control- beginning with the whole BS suspension. The other thing is- how many pinks do you know of that are as investor friendly as MTEK has been?
