No leet/text speak - eg: Lets c whu cn m@ke teh most complic@ted l33t spek ev@rr is not acceptable. A lot of users here have English as a second language and have a hard enough time understanding as it is. To that end, please make an effort to use proper grammar and spelling. We don't expect everyone to have perfect textbook English, but the clearer you are, the better you will be understood, and the more response you'll get to help questions, or any post in general. We are not the grammar police here and understand typos happen and not everyone is a perfect speller, but if you're not using periods, commas, capital letters and a reasonable semblance of accurate spelling out of pure laziness, we will call you on it.
