Fields not working in Membership Management module

You are making me think that allowing template variables where there are currently mailto links could be a good idea... I will give you that...  

Right now, though, they are just plain mailto links.

I vote for the enhancement, so that I use my template when contacting a meeting participant via the agenda, but considering it more today, I suppose it's not terribly important, since I'm contacting ONE person and it's easy enough to simply type her name.  All my other templates relate to sending the agenda via e-mail or sending e-mail to folks/groups in the Membership Management module, where variables are enabled.
Maybe one day when you're really bored.  :<

FYI: When one does send via agenda line item, the advisory e-mail sent to the sender does mention variable replacement: "The following email (w/ any variable replacements) was sent to: Joe@Blow.com"
