Colin,
I have no idea why you would quote my post in your rant on sarcasm. I've not been sarcastic with you. Indeed, in my off forum emails with you I've explained what I'm going through personally so you would better understand why I don't give you extended, verbose replies on the forum.
No one has given you any reason to take away your rugby ball and go home. Forgive me, but I simply don't understand. But be that as it may, you can stay or leave, as always, it's up to you. No one told you to do anything, no one was sarcastic towards you and no one called you any names. I believe this is all a huge misunderstanding on your part. But that's just my personal opinion. YMMV.
