On the point of people not speaking English as their first language, most do speak a better one then lot's of natives so not really relevant. We can make grammatical mistakes but JD and EddieC points are absolutely spot on.
Starting a sentence with a capital letter is a rules of grammar, so you speak English or you don't. Oh and Lil Cisse, there are no such thing as "text language", if you are using T9 on mobile to type messages, it's doesn't come out with all these abbreviations, it's called laziness not text language.
This is the way JD and other moderators want it and that is the bottom line, live with it.
Also, don't forget that for a lot's of us, (none native) using this forum is also somewhere to improve our English, so people moaning about this rule should think about that and been proud of their language.
