I play Dutch Acol(strong 1NT) but for the rest it's pretty much the same. The whole system is pretty much based around the opening structure: longest suit and lowest from four card suits. You should never miss a fit(partner should always prefer bidding a major to supporting a minor). The only exception is if you play fourth suit as conventional(you might miss a spade fit then on a 4-4-1-4 so 1H is preferable instead of 1C).

I know this is illegal pretty much everywhere, but is enctrypted signalling allowed on BBO?

Nice to see a thread on this. I am currently learning Precision with my partner and we came across a few 4-4-4-1 hands in the opener's hand(=no impossible negative). I agree with rebidding 1NT with these hands over a positive 1-level response, but what to do over a negative? 1NT is a natural 16-18 No Trump opening now and the singleton is really a problem(1NT over positive is not necessarily a balanced hand).
