This is a very interesting post, I too was a bit baffled by the initial posting but after the clarification 1/2 way down the first page I find that I wholeheartedly agree with Alan's comments.
There are indeed very few, if any "experts" here, those that consider themselves such, are probably best avoided

We have always been a community of enthusiasts. Nothing more, nothing less.
Of the registered members, at least those who I estimate visit the site regularly, I reckon that something under 2% ever post anything at all & are perfectly just happy to lurk. Regular posters make up around .5% of all registered users. This is fine, I certainly can't do anything about it, I am always trying to think up different ways to encourage lurkers to become posters, it is however almost impossible.
To be absolutely honest, I find the "excuse" that "I wanted to post, but was worried about getting shot down in flames" pretty much unbelievable. Any regular reader of the forum MUST know that here of all places it is very, very rare that this happens, disagreements are usually aired in a most constructive way & the members not to mention the very conscientious team of moderators simply don't allow this to happen.
Posting is easy & free to do, all that is likely to happen is that you meet new friends & if not learn new stuff, then certainly hear about various differing points of view, something that can only be good.
I have to be honest & say that in this age of fragmentation & the proliferation of social media sites like Facebook, I believe that the days of a truly independent site like this are numbered. Regular posters & new regular posters in particular are our life blood & it has to be said that over the last few years the number of lurkers has increased & the variety of posters has reduced.
I have always said that this site is only ever as good as the content posted by the members & without people prepared to contribute it will wither & die.
So, on a more cheerful note, read this & make your first post, it doesn't matter what it is about . . . just do it, you won't regret your decision to get involved, it's much more fun than watching from the sidelines.
