How do the backgrounds work?  I was thinking about making him an actor (imagine an acting troupe of changelings).
		
		
	 
As mentioned, the background traits from the PH2 and AP (currently) give you either a skill as a class skill, a +2 to a skill, or a language. Your can make up the rest of your background as you wish, but you should choose a trait that (1) fits your background idea and (2) makes sense to you mechanically. Gunpowder has the right of it above.
	
		
	
	
		
		
			Another thing I'm confused about is the proposed treasure/wealth for a new character.  I'm tempted just to make my character lv1 just to avoid parcels.
		
		
	 
I assume this is after reading what I wrote on the 
Character Generation page? I'll post it here again (I made some further clarifications:
As an example, consider Harbinger, a 4th level human Avenger. He can choose three parcels: A parcel earned at level 1, one at level 2, and one at level 3. One valid set of parcels are:
-  1st: A level 3 item (He chose the n+2 parcel for level 1; 1+2=3)
 
-  2nd: A level 5 item (He chose the n+3 parcel for level 2; 2+3=5)
 
-  3rd: A level 7 item (He chose the n+4 for level 3; 3+4=7)
 
In addition, he would receive 412gp: 100gp initially and 312gp representing 1/5th of the cost of a level 1 (360gp), level 2 (520gp), and level 3 item (680gp).
 
	
		
	
	
		
		
			Wow, I just wasted 2 hours on editing my character page to result in a halfway page with all wrong numbers.
		
		
	 
I assume you are talking about the 
Skills and Languages section; the rest of the page seems fine (though partially complete). The key is all the text in the brackets (the "[]") represents values that are optional, but you must remove the []'s for it to work (if you note on the sample sheet, the brackets are not there). So, for example, for the Arcana section, you had
	
	
	
		Code:
	
	
		|ArcanaTrained=5
|RaceBonArcana=[bonus from race]
|FeatBonArcana=[bonuses from feats]
|FeatNameArcana=[name of feats]
|EquipBonArcana=[bonuses from equipment]
|EquipNameArcana=
	 
 where it should be:
	
	
	
		Code:
	
	
		|ArcanaTrained=5
|RaceBonArcana=
|FeatBonArcana=
|FeatNameArcana=
|EquipBonArcana=
|EquipNameArcana=
	 
 Note, the brackets are removed. Removing them, the template works. Just be sure to remove brackets if you use the original templates.
