I am also a social media refusenik, so forums like this are my natural habitat. Although I do collect GB bronze and copper, I also like all the GB silver and some older foreign pieces too. Like @Sylvester I found the bias towards bronze and copper pennies a little disappointing. There are some great experts in all areas on here, but we need to encourage them to continue showing up occasionally or the forum will die.
I think also, some posters here are a bit aggressive with their criticism if they disagree with a poster's viewpoint, which simply drives them away. Of course we can disagree, but it needs to be kept non-personal.
