There are a few ground rules for participation in blogs and forums. Please respect these rules, and each other.
No personal attacks. Do not feel compelled to defend your honor in public. Posts containing personal attacks may be removed from the news server.
Stay on topic
Most of these groups are high-traffic and read by busy people, so please pay attention to the topic of your messages, and check that it still relates to the charter of the forum to which you are posting. Off-topic discussion IABSE will remove or take to any place where it is not considered off-topic, by someone who knows they should be taking it elsewhere, is eligible for removal from the news server.
Be kind to newcomers
Newcomers may be annoying. They ask the wrong questions, including ones that seem obvious (or whose answers seem easy to find). But lots of valued contributors started out this way, and treating newcomers kindly makes them more likely to turn into the valuable community members we all know and love (and cut some slack when they mess up).
So while you don't have to humor them or suffer them gladly, and it's fine to point out when they make mistakes, point newcomers in the right direction in addition to turning them away from the wrong ones, and be kind to them in the process of correcting their transgressions.
Let sleeping dogs lie
It's tempting to revisit controversial decisions you disagree with, but it's rarely productive to do so, since it almost always results in the same heated, lengthy, and time/energy draining discussions leading to the same conclusion that was reached in the last round.
Therefore, for issues already raised, discussed, and decided upon, reopen the discussion only if you have significant new information that would reasonably prompt reconsideration of the original decision.
