I for one am getting confused by all the possible ways of identifying the objects. Im the posts I have read, I remember at least three terms:
and I suspect there are more. Coordinates is somewhat self explanatory, though where to get these is not. I think the intro tutorial could use an eplanation of these as well as how best to post these to the forums. (I know there are post on how to do this, but it should be easier). Also, those using Fire Fox, Opra, etc. browsers need to understand that those are not standard browsers and their suggestions, unless the browser is specified, may be quite confusing..
