Welcome Pennygril -
Nice to have another female here! There's not many of us but the guys are a sweeties so not to worry! You won't find a friendlier or more helpful group anywhere.
Definately get a good meat thermometer most here like the newfangled digital ones. Maveric I belive is the favorite. Personally I like the dila types best but I'm in the minority (in more ways than one). You'll also want to calibrate it by putting it in boiling water - i should read 212 degrees at sea level.
