Wiv u dere, Loosehead :-)
Anyone can make the odd typo or put an apostrophe in the wrong place - I've even done it myself (I know, almost unbelievable, but true), but "txtspk" and its inbred relative chavspeak are not only inconsiderate to those of us who have to read them, they also makes the author seem a little bit, well, slooooooooow. I imagine them saying wiv and dat and da (instead of the) in real life - makes them sound about two years old.
Puts the odd missing comma into perspective.
