For the record... I also like the "smoke"... at least there's a possibility that "fire" might happen at some point.

For what it's worth, I have resisted (refused?) to incorporate any
Facebook links (or password substitution) into my forum. I don't think that creating that kind of "trust" is in my best interests.
In fact, I'm VERY suspicious of all other services (commonly known as Social Networks)... Beware of who you THINK YOUR FRIENDS ARE. Or in this case, who your
business partners are. If you can't call your "partner" on the phone, why the heck would you EVER allow a security link with them??!
My 2 cents.
