Sending Contact Group to another user

[timm@bicyclegermany.com]

My apologies if this turns out to be a duplicate. The first posting was classed as spam (which it was not) and I am reposting.
I want to know how to send an entire contact group to another user without sending the same email to everyone in the contact group. I have tried the forward button but neither option under that works. One option ends up as an .eml file than cannot be opened by anyone or anything, the other option becomes a text file that a human cannot read. How can this be done and why is it so difficult. I have tried for 3 hours to find a solution without luck.

Hi Clark,

I tried your suggestion and I clicked on the link your reference. Neither worked. What I get, is what I got before I posted the initial query - an attachment on the receiver's computer that says "Untitled attachment ... .eml. I am using Google Gmail. I think that is the problem. Somehow, outlook attachments are changed to files with an eml extension.

This cannot be an uncommon occurrence, can you recommend someone else I can query or go to for help?
