In the FAQ's it says:
The use of "Lingo"
We do not allow members to use "lingo" on our site. Please take a few extra moments to type out words such as "anyone" and "your". Excessive use of lingo may result in your posts being deleted, and in extreme cases, temporary banning from the site.
It seems you expect people to write do not cannot, will not etc. instead of the normal "short" versions. I see that all the time, I wont, I can't etc. and I'm using it all the time. Is the purpose of posting to write something worthy of homework in english? But if this is the rule to obide by, I will think for a moment, so as not to write "can't" when I can write cannot. Personally, I find it much more iritating with the use of lol, XD etc, some of these "abbrevations" I have no clue what they mean.
