Ah yes, I see a couple of names in your signature I'm quite happy to hear what they have to say / present, but hey.. no harm in a difference of opinion.
Franspeakfree, I think Robbie maybe feels he's done his bit and got off his chest what he wanted to say on the UFO subject. Sometimes when you're at a forum, this sort of thing happens - suddenly there is nothing more to say. We all go through those stages as forum members, I'm sure Robbie's no different.
Sometimes it takes an interesting new story to spark renewed interest (for me, it's the crop circles), maybe Robbie will post again when he feels like chiming in. Until then, long may he peacefully lurk!
