Dan,
I could prune a lot but in the interest of lively conversation I have let things stand that are not necessarily Science. Take it easy, you don't have to have 100% Science in every post to be a science forum. You do have to know when to overlook and when to oversee. Lighten up a bit and try to have some fun. You'd be surprised what it'll do for your morale. Save me a glass of the good stuff, will you? I want to talk to that invisible purple rhino too. smile
