Why? OK. I must have got several hundred likes by people who, going on some of the inane replies, I have to assume did not read the question at all. With the exception of a few they kept giving me advice on El Cid. anyone with a rudimentary knowledge of the Reconquista will know that Roderigo Diaz de Vivar was not present at Fraga and having been dead for 113 years didn't manage to make it to Las Navas de Tolosa either! :>)
Maybe by adding a few pics of books received in the mail recently the question might have led to the 'appearance' I was asking a different question
Three of the commentators were really good and offered quite legitimate advice which I have taken on board so a huge thank you to those who were willing to give up some of their time and offer guidance.
In general though, I think it goes without saying that I will be avoiding asking similar questions on Facebook again!
Perhaps more disturbingly is the move away from what was a thriving fora community to that of the more fleeting dividend that people get, the endorphin 'rush' that we as a species are prone to seeking with a simple "like"! With the possible exception of The Lead Adventure Forum and The Miniatures Page the heady days of getting a detailed answers to ones queries seem to be well and truly gone. This is a loss to us all. Social media culture has truly permeated out hobby to the point that it seems meaningless to ask for advice on the popular Social Media platforms.
Please do not get the impression that I'm some sort of grumpy old man. This is just an observation, made several times over the past few year, but never articulated (by me).
