Any other dyslexic board users...
Try taking the extra step of typing out posts in either MS Word or Open Office Writer. Watch not only for the red squiggly line for misspellings but also for the green one. That will help with words in wrong places and 'off' grammar. Also try writing out your posts and then, before posting them, go do something else for a couple of minutes then come back and re-read your post before sending it. It's not fool proof, but every little bit helps.
FYI, I'm not dyslexic but I have other issues and I'm pretty good with coming up with things to help.
