I'm going to have to stick with SMF, since I have already spent time developing it, creating an autolink function, etc. Some of the admin backend is very nice, including an automatic upgrade feature for security patches, which I have already used. Furthermore, it should be easy to import old CC posts in here. SMF 2.0 shows a lot of promise! 8) I'll wait for that until it's out of beta.
Now, something that is worth considering, as far as what you are "used to," is that a ton of the main interface is controlled by theme settings. If you'd like to see buttons in a different place or whatever, it could probably be worked out.
And on the topic of rebuilding CC... I still haven't heard from Conor, but I may drop him a line again if I haven't heard from him by Sunday (a week from his first response).
