It's fairly simple really and helps organise things a lot easier if dealing with topics like contests, buying/selling, guides (see example below) and so on.
I'll keep this short and sweet as to not take up too much of your time.
Please be sure to use this function if you are creating a Buying/Selling thread in our Trading Post, once again, to help keep things organised.
(Anyone who does not, will receive a verbal warning to adjust their thread title (with help from us if need be). If the person does not comply within 48 hours, the thread will be removed.)
So, without further ado, onto the guide
1: Click "Start New Topic" as seen below
2: Type in your desired tag to use as a prefix in the 'Topic Tags' section. Then check the box that says 'Use first tag as prefix' (as seen below)
3: Format your topic as you would normally, using the Text Box for your content and finally, click 'Post New Topic' as you revel in the wondrous marvel you have achieved.
