Very little in my life would change, I'd move on and find a different forum. I also participate on Nintendo Life too, just not as much because I don't like that format. I mean, I like PC, it's a pretty awesome forum about Pokemon, but forums come and go, they all vanish, eventually, and get replaced by something else. It's the nature of life, to constantly change.
I don't know though, I may be a bit hardened after seeing a forum I use to moderate on, vBulliten like this, collapse. Politics destroyed a forum about politics, how ironic, no? Then I tried to help the spin-off group build a new forum, but that became tedious due to them asking how to code things while not giving me access to the admin pages and expecting me to make miracles happen.
The main reason I like PC though, the people here are mostly interesting, and there are a lot of cool members too. I'd miss it, but it wouldn't impact me much otherwise.
