Online monitoring

Hi, I have been offered the option of online monitoring by my GP. The endocrinologist is a doctor in Vancouver who reviews and replies to emails within a day or two. I thought it could be a good option because sometimes I just like being reassured but have things under control and only go in for yearly check ups with my endocrinologist. Also I'm pretty busy with work and kids so things get away from me but it'd be good to keep on track with a weekly or monthly email communication.
Has anyone else used a system similar? Has it been helpful, if you have?
Thanks!
