How do I send Contact info (VCard) via Gmail?

[jtmeyers]

When I open the details for a contact on my TB and then hit the Menu "button" there is an option to "Send Contact". Selecting this gives me 3 options to send the contact info as a VCard: MMS, Mail, and Bluetooth. When I select Mail and then click Send, it is being sent via my primary email account (which is a Yahoo account). I can click on that email account name to select another email account, but my Gmail account is not presented as an option.

Does anyone know how to do this (send contact vCard from Gmail) from the contact details screen?
