On behalf of the entire Python community, *thank you* for putting this
disclaimer only in the body of your message and using the Subject
field for a descriptive summary of the topic.

There are far too many threads where the only information available
from the Subject is "I'm a newbie, help!" which is worse than useless
for knowing what the thread is about. Thank you for not following this
tedious trend!
