    Re: Forum's policy on self promotion?

    Have we ever thought about adding a section to the forum for self-promotion? A sort of "what I'm working on" section or something for people to post projects and others to give feedback?

    Re: 'new' instantiating command ??

    On the left side, you are creating a variable, named object_name, with the type class_name. On the right side, you are initializing a new class_name object. This is an important distinction.
