That one is pretty easy, really. You can find other members by clicking the Members link on the top navigation menu. Click the Follow button for any members you want to follow, and you’ll be able to track their activities in your account area.
Find your account area by hovering your mouse over your username in the top right corner of the page. Then hover over Follow, then click Following, to see the activities of those you have chosen to follow. The page will show you how recently those members have been active. Choose a member to see what that person has been up to.
You can sort by the type of activities of those you’re following, and you can choose to look through groups that the members might have joined.
You can also click the Activity link on our top navigation menu to browse activity site wide, and look for members that way.
