Yeah, to be honest it just won't work due to the moderating problem. And not only that, it does partly make it awkward for other members - namely the majority, who don't speak Welsh at all lol! Plus as others said you've only got the handful who do really. However, if you really wish to speak Welsh with other TiBB members there are plenty of other chatting methods. The odd sentence now and again is OK so I don't see why people have been arguing about it. I'd just refrain from speaking it too much here and instead doing it elsewhere.
