How do I make it so that if I have a link somewhere in the template code (so I can't use mambots to do this etc), and that this link only shows if you belong to a certain group (e.g. author). So for example, if you are logged in as an author you can see this HTML link, but logged in as anyone else and you cant.
This actual code is for use in a component modification, but I thought the easiest way to explain it would be as above.
