Info on FC please

[gerrynix]

Hello all,

Which is the latest, and "stable" version of FC, suitable for a small business
server? How viable is this in regards to longevity, without need for (very)
frequent updates and/or version upgrades? Is it better to considering purchase
of a supported version? 

I believe there is a specific "FC" list, but I am unsure how to join. I've
checked the RH site.

Which are favored download sites for FC?
