Hi Angie!
Welcome to the Forum!
1. The continuous glucose monitoring system (CGMS) is a device that you wear, like a pager or insulin pump, to continuosly monitor your blood glucose levels. Most people do not have or use them, since they are expensive.
2. Adding a data entry can be done through Add Log or through Logs; My Logs using the plus (+) sign. Either way works.
3. I would advise you to read up on TIPS before trying it. Usually it causes new users problems with having logs they can't delete. There are several threads concerning TIPS on the Forum. There are several
links on the web as well.
I hope the information helps!
