[Story] - Used when a GM is writing something that is not a quest, but just information (it could pertain to a quest). If it links to another story or quest(s), then make sure to make a notice about that and link to them at the beginning.
[Quest] - Something that players can participate in. Links can also be provided to stories/quests that pertain to it. This kind of tag can have more specifics like this:
[Open Quest] or [OQuest] - The quest in that thread is still open to more players for participation. The GM can place a limit in his post as well.
[Closed Quest] or [CQuest] - The quest in that thread is closed and no more players may participate.
[Plot Story/Quest] or [PStory/PQuest] - Same as the tags above, except these relate to DarkStorm's overall plot and are posted by Cspace.
[Inn] or [Tavern] - DStorm inn or tavern, where a players can easily congregate with other players, buy sleeping quarters, food, drink, find roaming travelers created by GM's, etc.. Each inn/tavern should have its own name and innkeeper.
[Merchant] - Any shop/stall/hut/whatever that sells and buys items. Mostly found in specified marketing sub-forums within towns.
[Traveling] - Created by GM's and DStorm players alike. Whenever they make a thread where they're simpling traveling through regions (usually connection regions), they can use this tag. There's usually a lot of these threads, so the tag could help differentiate these from things like quests. However, we always leave this tag out so that Quest/Story threads stand out more.
