There are an awful lot of support requests lately asking "how do I put my journal link in my AIM profile" or "what link do I use for my journal? I want to put it in my profile." Adding a paragraph to FAQ 104 ("How do I create an account? How do I get started?") with an example link might help. At least it will give something consistent to point to in these types of requests.
Once you have created your account, your journal will be available at an URL similar to the following:
replacing "exampleusername" with your LiveJournal username. You may give this URL to friends for them to view your journal, or include it in your instant messaging profile or other websites and profiles.
