This message is not being sent secondary to any incident, but because it's useful information to have regardless of whether an internet forum or e-mail list is involved.  Much of what it contains used to be "common knowledge" but in recent years its communication "down the generations" seems to be getting lost.  It's too valuable for that to happen.

25 Forum Posting Etiquette Tips

The article above was originally posted all the way back in 2007, which is eons ago in the computer age.  It has withstood the test of time, with the exception of recommending against using HTML formatted messages, as these have become a de facto standard since. 

One addition to that list should be:  Please, when you send a message asking for assistance and find the answer yourself prior to someone else having managed to do so, don’t post something like, “It’s OK, I fixed it.”  It's rude to leave the readership hanging  once you've determined a solution. If you were looking for how to fix it, later searchers will also be looking for that answer.  Since you know how, add the, “and here’s how,” part afterward.  Many will bless you, even though you don’t know they do.
