Unfortunatley, you can't turn buildings. If you really want to turn a building, you must go into the object editor, and change the value called "Stats - is a building" to false, and then turn it on the map like you would a normal unit.
Which, if you don't know, holding down control and then clicking where you want a unit to face, with that unit selected.
If you create the buildings with triggers, you can rotate them while you're creating them.
Otherwise, make the building a unit, rotate it, then make it a building again.
da1nONLYEd's right, you can't rotate a building, and you can go into the Object Editor, remove "Is a Building" to then rotate it, but as long as you don't need it to be built in the game, you can go back into the Object Editor after you've rotated it and re-make it into a building so everything works in the game.
The problem is that you can't rotate buildings that are built... I found a perfect Warcraft II "Altar of Storms" model that's facing the entirely wrong way... :banghead:
I don't think I'm dealing with quite the same pressures though, at the very least its a significantly smaller system. For the time being I'm just going to put together a quick scrubby box though and hope it works good enough to not make my house toxic
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
