Forums are very much a competitive exercise. I see your keybonics, and raise you proper english. You have to strengthen your vocabulary, and your grammar skills. Few things will bring down the ire of a web based community like a lengthy incoherent ramble. Call it elitist or arrogant, but its just common manners online. When you do not make a respectable effort to convey your thoughts in a thoroughly understandable manner people will take offense.
To get respect you need to be respectful of others who will read what you write. You need to slow down your typing. Check your spelling. Use proper punctuation. Periods, commas, and capitalization are critical for differentiation. Nobody is expecting great oratory. They are just expecting that you take the time to do a decent job.
You do not need a spell check to improve your grammar either. Honestly that can become quite a crutch. However if you dedicate just a few minutes each day to learning a few new words, and take the time to review the rules of grammar you can improve dramatically.
I am not sure what kind of schools everyone else went to, but had I spelled anything like what you have. I would have gotten detention on the spot, and not for just a day I would have spent weeks in detention. I would have had a tutor forced on to me, and I would have received additional homework until my writing was on par. Perhaps the schools I went to were better then most. However I find it hard to imagine any school intentionally letting a student do this miserably. Say what you like about standardized testing, but it does ensure that students get the basic skills they need.
Just my thoughts on the subject.
