Posting a patch to a development mailing list with something like
*** please do not ignore ***
at the top of the email is quite possibly the best way to get me to ignore your email.
News flash people! Open source developers review patches sent to mailing lists when they have the time. They're not going out of their way to ignore anyone, and implying that your patch is somehow special and deserves to be dealt with rightfuckingnowdamnit instead of when the developer has time is just egocentric and rude.
