@Sphinx No clue, I don't use those. I've always relied on trying to improve my knowledge manually. English is not my first language.
In fact, I usually turn off spellcheckers whenever I see them, because those red squigly lines distract me. :)
@Sphinx If you want I can respond to some of your posts to correct your English now and then, even if it might not have much to do with the contents of your post?
@Pat The mere fact you know your posts have grammatical errors isn't making me jump up fast to correct you. ;) Oh, I might if I spot them, but I'm not 100% paying attention to those.
Whereas @Sphinx genuinely wouldn't know if he made a mistake, so I'm willing to help him out there whenever I see that.
