Hi boosters, We use boost too, here is my "report". Application: Rule in Hell Company: Megahard Software Technologies Inc. Description of Application: Massively Multiplayer Online Role Playing Game (still in beta) Boost libs used: bind function any tuples ref shared_ptr type_traits noncopyable By *FAR* the combination of bind, function,shared_ptr and ref is what we use most heavily. As time goes on we tend to replace our custom code with boost libs that perform more or less the same functionality (where it makes sense) url: http://www.ruleinhell.com
