I agree Dave and thank you for the supportive post. I've just installed an upgrade which will make the Forum more visible on Social Media, where the first post in a thread can be shared to your Facebook page. You may not have noticed the 'Share' link at the bottom of the first post in a thread.
CliveH is a member and I'm in touch with him from time to time. He's already a published author and is somewhat busy at the moment. He has promised to post stuff he's expert in (Defences and Fortified Places etc) when he gets time.
In the meantime, I'm more than happy with how things are going right now and as you say, it will build momentum over time.
