Its simple. Archanum posts must be tagged by where they are taking place and where within that place the post is taking place.

For instance.

Sialis: City Area
Sialis: Back Alley
Sialis: Corner Store

Something along these lines is fine. Make sure you are correct and area specific on this. If you are out in the wilderness. Which wilderness?

Sialis Outskirts: Open Forest
Sialis Outskirts: Hermits Cave
Sialis Outskirts: Dive Site

And finally within larger places.

Sialis: Military Facility: 3rd floor

If you are having problem with the space cut off the last part. Not the first.

This:
Sialis: Military Facility: 3rd..

Not:
3rd floor.

The only other posting requirement is that you have a character and have read the rules. Have fun guys. ^^
