Regarding spell-check, why not just set your computer to automatically check all outgoing text no matter what site, e-mail, etc. that you're on?
I'm using an older laptop right now, but even using it, the auto spell-check works just fine on this website. If I didn't have it selected, it would be "typo city" for me.
p.s.. This has probably already been answered. But there's a ton of responses on here and it would take forever reading all of them. ~LOL~
