I missed a year or two here and there myself.
We've gone the opposite direction - I don't remember how many kitties we had when you left (though because we used to foster there were always extra cats around) - but we've got six now.
Things haven't changed as much as they look like they have.
There's a LOT more members, and a lot more activity. The points system is fun - you get points for posting, and you can buy "gifts" for other members with the points. It's cute. You can also put them in the bank and buy interest, so they start adding up.
There are more forums and sub-forums. But it's still a friendly - and amazing - community.
I don't remember knowing you had to rehome your kitties.
I'm so sorry. I can't imagine how hard that must have been.
