Answering questions like that is insider info.

How can you expect a response?

The HITS part can be viewed negative if the # is low, thus they will not advise such.

The thing to do is say this on proto types.

"Hi Fred, at the appropriate time, please update us if you can as to proto type testing, shareholders would like to know."

Then say, "no email reply expected."

Be a wordsmith...lol.
