In all honesty this fanclub should have been started a year ago, there seemed to be a little more interest in this pair back then. Of course I think that interest was coupled with the idea that Kakashi was going to be Hokage and that plot development got derailed.
I still contend that this is an awesome pairing. Mei, the age conscious busy-body who reformed her village, and Kakashi - the world famous shinobi with scars both physical and emotional. Mei needs someone stable, not to mention her own age; Kakashi would find in her a strong woman, a survivor, someone he doesn't have to be afraid for.
As far as their personalities go. They're both flirtatious as sin (see the DS-Hina fanart for ref.) They play around with their words psyching out others (more often than not their allies) for, what I perceive to be, their own amusement more than anything else.
There are physical factors to be considered, but I'll let those speak for themselves.
Hope you like what you find.
p.s. Also, if you're on NF, don't be a stranger and drop by the FC there: Hot Steam: The KakaMei FC
