It's always a shame when someone feels the need to resign (or semi) from a forum such as this but it has to be remembered that times and people do change.
I have been a moderator on an engineering forum for over 19 years now and it is noticeable how the users (members) interest changes over time. There is an initial keenness to be in contact with like minded people and to share experiences whether gaining or giving knowledge.
After a while the realisation sets in that you know as much as you need too and you no longer know more than those asking the questions. You also notice that the newcomers queries begin to get repetitively similar and suggesting that the search facility is used normally falls on deaf ears.
There are times, no doubt, when moderators may seem harsh but consider also the logistics of the forum. There is minimum advertising here because it is, I believe, run by a commercial enterprise. The owners therefore are entitled to set some rules and live by them. If these rules do not sit well with you then of course you have the right to stand back.
I do find it a shame that Barrie felt the need to publicize his disagreement with Jason as it does not allow Jason to defend his position and as such seems somewhat unfair. A quiet departure with PMs to close contacts would have been more diplomatic.
