I learned lojban for c. 18 months some years ago. It is a completely constructed language with a grammar that is as unusual as it is regular and unambiguous. Among the many advantages (aside from being a beautiful language) is that this way you can construct a sentence over 20 pages without having to fear that the computer reading it gets confused by the grammar; one of the disadvantages is that there are somewhere around zero really fluent speakers.

Yesterday I was thinking about becoming fluent enough in it again that I can host Language Hunting sessions for beginners for let’s say up to two or three days without struggling. The idea is that I can be pretty sure that when demonstrating the game, there will be nobody around who is already familiar with the language; another is that it can be shown that even very unusual, seemingly complicated languages (in reality lojban is really regular, just different from natural languages) can be easily grasped with this technique. Another valuable point would be that nobody would be tempted to stress themselves out because they are feeling they have to learn this specific language, making it very clear that this is about a technique for hunting any language. On the downside, people may be put off by the geek factor. I guess there’s only one way to find out :)

There is already a (dormant?) project to do WAYK with lojban (the aptly named lo do ckiku ma zvati), I’ll check out if Alan wants to do some online sessions maybe.

I just remembered that I did play a short session lojban/WAYK with an ex-flatmate quite a while ago. It was fun, but I found that I was at that point not firm enough in lojban to go as fast as I would have liked. She remembered “plise” together with the sign some weeks later :)
