Been here a while, but only now on message boards

I have been using other programs for a bit and now have been on MyFitnessPal for a month or so. I like MFP a LOT becasue it is soooo much easier to find foods. My immediate goal is to lose a 115 pounds. My wife is also on the boards here (she is JonnaGrace). I have posted a couple of blogs here that give some background on where I come from on all this. Love to hear from anyone - my main interests:

The technical, bioligical, math oriented part of it all
Working out with sore knees
Using the Wii (Wii Fit, Active Sports)
Resistance tubes
Exercise ball
Recumbant bike
CSA farms
Canning
Frugal (but high value) grocery shopping
