I include myself in this because I've left out words that totally changed the meaning, or transposed letters, used the wrong words, left out a key phrase. I don't usually misspell cause I'm a pretty good speller. But I wish we'd all try harder.
Here are a couple of things I can think of:
o the word is avOcado not avAcado
o the word is "have" not "of"
o lack of capitalization is annoying
o I'd like to be told when I've misused a word. For instance, I never thought about "panini" is the plural so "paninis" is wrong. Now that I know, I'll try not to make THAT mistake again :)
o ALL CAPS IS SHOUTING :)
o Could we all take the time to proof our posts before sending?
Are there other things you can toss into this pot that we can learn from. I'm sure I'm guilty of things and would like to be less annoying to those here who put up with ME. This is probably going to get deleted because we're not supposed to tell people what to do but I'll run it up the flagpole anyway.
