Roger,

I could probably get you in as I own a formal, legally registered organization for doing research. And you could use an E-mail address connected with one of my Web sites.

I tried to access the ResearchGate site but got no response. That probably had to do with my virus software settings. I have to change them all the time just to store notes on my own Web sites.

I have not yet joined LinkedIn because the group requires too much personal information. I wonder how much ResearchGate requires.
