Using the correct forum for your post
Using the correct forum for your post. Bug reports and idle chatter do not belong on the gentoo-dev mailing list; discussion about a wide-ranging change to the tree probably does not belong on Bugzilla.

Use concise and clear language. The Gentoo community includes people from all over the world, with varying English skills and available time.

Admit the possibility of fault and respect different point of views
Admit the possibility of fault and respect different point of views. No one is perfect – you will get things wrong occasionally. Don't be afraid to admit this. Similarly, while something may seem perfectly obvious to you, others may see it differently.
