I'm fairly new around here and until now have only posted a couple of
things, but I think its dissappointing to see Steve quitting the list like
this.
I don't know the background between Phil & Steve, but surely it could be
sorted without anyone feeling they have to quit?
My 2 penneth, now I'll mind my own.
