One set of eyes just isn't enough!
I sent out an announcement to clients this morning about some seminars I'm launching and -- wouldn't you know it -- the announcement had a typo. Instead of Plain Language, I typed: Plan Language. Of course the spell checker didn't flag that because "plan" is a perfectly fine word, as far as the spell check program is concerned!
Well, nothing I can do about it now other than use this as a "teachable moment" and a chance to remind everyone that if it's something important you're putting out -- it's always best to ask someone else to proofread it before you send it. I know, finding someone to proof something isn't always easy, especially if you fly solo, like I do. But, live and learn... (and try to find someone next time!)
