Feel free to PM the person who made the typo. Report it to us too and say: "Pssst! Can you fix the word TYPO-O in the title to TYPO please?" It ticks me off too. However, it is also an indication of the attentiveness the OP puts into his own writing. There is some value to that. If you receive an email with a spelling mistake in the subject line, what is your automatic thought of the sender? With 99% probability, where does that email belong?
