Absolutely anything, whatever yourself or any other member wishes to boost. It's essentially a very large trading thread where people help one another it's required by both parties.
Do you boost? If so, please feel free to join my boosting social group, I'm always on the look out for x360a members that have half a brain cell between their ears... One of the more important aspects of boosting in my opinion. The others being dependability and maturity.
Anyway, if you want to join, there's a place for you.
