You did a great job using the site...you can click on your avatar and to the right of it is your content...then you can see any of the blogs or conversations you have written. On the left side of the page, you can click on things you have participated in, authored, recently viewed, etc. When you sign in, you can go to HOME and see recent blogs and updates, you can choose to follow people, hover over their name and a drop down menu should come up that allows you to follow.
I am not exactly the most proficient user of the site but I can help you a little bit.
If you live with someone who smokes...ask that person not to smoke in the house, ask him not to leave cigarettes, lighters, and ashtrays laying around. It will help you and it will also help HIM to cut back whether he means to or not. I did not smoke in my house and I really think that helped me somewhat when I quit...standing out in the rain and snow or heat and humidity is not my idea of fun. Hang in there and stay close to the site. I came here every morning and every evening and still do for the most part, even after more that 4 1/2 years...it HELPS.
