I appreciate your help and I understand that it may be very frustrating when a noob comes along.
I have calculated my BMR and it is around 2100.
Is this how much I should be consuming?
Yes

I was just about to tell you to google "BMR calculator" to make stuff easier but you can still double check. As you lose significant amounts of weight, that number will change. That link Kara gave you explains perfectly but you do not want to eat under your BMR or too far over.
I know it's frustrating and we all want to calculate how many pounds we could lose if we just cut back to the max and increased to as much activity as we can tolerate, I used to do that. But just eating at my BMR I'm losing more than it says I should be if I do those numbers games. So that tells me my body is working with me, not against me.
And here's something else to think of. I used to think I had to start at 1200 calories, do 3 hours of exercise a day, etc. I'd jump in with this all or nothing attitude and sooner or later I'd hit a plateau that I couldn't get past because why? Because I'd left myself nowhere to go. I couldn't cut back my calories anymore or push harder than I already was. Eventually I'd quit. Thank goodness I figured out weight loss doesn't have to be that miserable process.
So yea

Read the stickies as you have time, it's well worth it. You'll find there's alot of awesome info here and support. Good luck. ~Lisa
edit* I'm no expert and this is what I've drawn from what I've read, I'm sure there's more to it by far. So I can't stress enough for you to read the stickies when you have time and process the information for yourself. We're all different and well as our bodies and discovering what works is part of the journey.
