A rather obvious point being made at someone specific on the board of course, but I do agree. People seem generally too lazy now, as opposed to lacking the intelligence to type legibly.

Even when I am sending sms I use full and correct grammar whenever possible, even if it takes longer to create the message it is more easily understood than the likes of "c u 2moz" and such, which actually would take me longer to understand than the full text would.

When using instant messenger programs I may often abbreviate, not due to any laziness, more to get a message sent more quickly, but never to the extent of the "txt" language.

I like the idea of only allowing people who will actually type to the best of their abilities, as you said it isn't to discriminate against those who are learning English as they often don't know well enough, but just those who are genuinely lazy. It would reduce the numbers of posters here significantly and those left could actually have proper, legible conversations.
