No worries, I'm the queen of typos and I can't edit any of them in my responses to posts without deleting and resending.
Don't have the edit function either. [Personally, I think the edit function is overrated and sort of silly - you end up getting multiple emails when people edit. You get the first version, then the second version. In one thread - someone edited their post five times - so I got five emails of the same post. LOL! I wonder if people realize this?]
