You can add other users to your buddy list very easily. When you come accross a user who you'd like to add as a buddy, click on that user's name or picture, and you'll be taken to their profile page. Find their list of "My Buddies", and at the bottom of the list, you can click to add them to your buddy lists. You'll then be asked (just to be sure) if you want to add this user; just click "Add".

Before the user becomes your buddy, they'll be asked to confirm. Once they do, then they'll show up on your buddy list (and vice versa).

If you're wondering how you might come across other users, you'll soon see that this can happen in many ways. For instance, you might be looking at a pattern. You'll notice a block to the right of the pattern telling you about the author. Simply click on the author's picture, and you'll reach their profile. Or, click on the "People" link near the top of any page to see who's online and who's recently joined Crochet Me. Again, you can click on a user there to go go their profile.
