Hi Steve.
I can assure you that your location/nationality are not used in any way as a measure of your 'worth' here at IIS. We have members from all over the globe who happily participate on this site.
Sorry you are feeling ignored. I'm sure it's not intentional.
Just keep posting away and joining in threads.
People will get familair with you and then it's a case of regular posting.
As far as the sarcasm or facetious humour goes? That can sometimes just be the Australian way of having a laugh. It's in our nature to be irreverent and our wit can at times border on the robust! As they say in the classics...'we mean no harm'.
Welcome....
