I've scene a lot of questions on how to to do this, so here is a short nifty tutorial.
step 1First of all, if your on the main site this isn't going work. Go to the fourms found on the top of any AS site.
Once you are there go to the user control panel.
Step 2Click on profile.
Step 3scroll to group/pack and add your test. Then just press "submit"and your good to go. This will also appear on site comment boxes in a blue text.
Hope this solves this frequently asked question.
