Dear Polonus,
I have no idea why you left: I just read in another thread that you are no longer on this forum. That is what motivated me to write this message.
Please reconsider your decision. This forum is frequented by many wise people like yourself, Essexboy, Tech (just to name a few). Moreover, the expertise, friendly advice and useful information which you provide have been a refreshing and invaluable contribution to this board.
I think I speak for many (other silent) users on this forum who enjoy, and profit from, reading your posts.
Hope to hear from you again and have a nice weekend.
Best wishes,
Avastfan1
