Thanks for the link, jeffp. In my first browse round I couldn't see any way to find info about UK lodges, so I'll have to go back and dig more deeply. The tone of what I did see was more open-spirited than printed leaflets I remember seeing some years ago in the UK, which were full of abbreviations like TTOBTR (tongue torn out by the root, I think).

One thing puzzled me. A page addressing the question "what is freemasonry" was full of curious, and on the face of it inexplicable, wrong words, albeit phonetically near-misses. Thus: winch for which, mariner for manner, waits for wants, etc, etc. It's the sort of thing I've been known to do since using text processors instead of typewriters, but surely no-one else has this affliction. There must be some other explanation.
