I, like Uncle Dave, am given to proofreading, but still some goofs manage to get through.

On a one-liner or very short post, I will type it in the message box and read it over (generally previewing it) before I submit. But if it's a longer one (which is often my wont), I type it into Microsoft Word (any word processor will do), check it there, and when proofread, I cut-and-paste it into the message box.

But as I say, I often miss a few and the furschlugginer typos still manage to get through.

About the only way I can catch them all in a piece of writing is to let is sit for a couple of days, then read it. The typos jump right out. But when an exchange is going on a thread, letting it sit often misses "the moment" and it's no longer relevant.
