Re: Does this bug you???
Yes, I've posted from my phone or late at night, and have made many grammatical errors in my haste. It's always a good idea to "craft" your post, to make sure it's mostly perfect before posting it.
But Empress is right, if you change your post so that it says something different, or the same thing in a different way, you should let everyone know, or even get the DM's permission first, since many other peoples' posts might be based off what you wrote.
