FB is the poorer for your departure, Ian.
It's not too late to change your mind, if you decide that you can in fact continue to ignore the rants of grumpy old men (behaviourally, anyway).
I thought the retort to your comment on the Bert's thread was a joke, but perhaps it wasn't, as it seems to have been removed. It would have been "grown up" for the removal to have occurred in conjunction with an apology!
For the record, your contribution there and elsewhere n this forum have added value to my experience here. Sorry to see your farewell post.
