Have question(s) still with my FitBit

NancLH4

I have my FitBit and love the readings and such that I get. But it's confusing. Where do I log everything in at. MFP says to log food and exercise here. That's fine, but won't the exercise double count on my FitBit log? I've seen a lot of questions asked within the page that is just explaining how the FitBit works. I think it would make a lot of sense to start a main topic so that all the questions about the FitBit could be in one area. Maybe even with a stickie to the top of the page for awhile. The same questions, are all over the place and hard to find, unless I do a seach, which just lists the different questions concerning the FitBit. I have no idea which forum those questions are in.
So...is there a way to add a stickie for any and all FitBit questions so that we can all benefit from the Q&A's that are already out there?
And do I log my info at MFP? Some of the answers are so long and back and forth with what we should do, that it's very confusing.
Thanks!!!!
