I recommend you join the free tier first where you will be able to see what resources are available for look ups etc from tier 2
Thanks - I already did that but there's very little to see in the free part. All the queries refer back to the parts I can't see and otherwise all I see is lots of chat. As suggested here I probably won't bther and will stick to Rootschat and Talking Scot, at least for now until I run into a brick wall

Thanks very much to the kind lady who shared her experiences of the site by PM. I'll try to reply now that I have enough posts, but if I don't manage, hope you see this, and my thanks.
