Re: Feedback from VOQL-TEG

Hi Jeff,

thanks for your mail.

Indeed, you have already provided invaluable inputs to the voql-teg through the AstroGrid representative (Kona) and I really appreciate that. Of course you are very welcome to give her inputs for our next meeting on possible region constructs... Your inputs are highly appreciated.

I look forward to it.

Thanks again,
P.
