A public answer is in order....
I sent the e-mail to ir@silverado.com per their website.
Question:
How many share holders of record are there, held in street name by a broker?
Knowing this info is not at all significant, but it's an indicator of market interest.
I sent this question to EDIG's IR contact and got an answer the next day..2869 as of June-09.
Give it a try if you like...thanks.
