People who post to get people upset about something and no one ever comes back to up date it.
People that ask for free fabrics, then comes back and tell they just bought a new sewing machine and took a vacation. Seems to me they could buy their own fabrics.
Poeple not looking at other threads and asking the same question that has already been asked.
People skipping around and not reading through PDAs, threads and asking a question that's already been answered, sometimes right above their question.
Too many more to mention.
