Hi Elias,

Thank you, this is excellent feedback. I am literally minutes away
from sending out an email to this group soliciting 2i feedback to
help us focus our efforts.

We have a rough idea internally of what we would like to do going forward,
but I'd prefer to gather feedback first before saying too much more.

Thanks,
Rusty
