David is busy. Give him time. He created this forum, and there is no reason to believe he won't do what it takes to keep it going. As Lori said, he needs to vet the person he would choose to moderate.
Those who want to help keep things running smoothly can do so by....
Not responding to trolls and troll-like comments. Threads that are inactive will automatically close in a short period of time anyway.
If you feel the need to rant about what you feel is an incredibly [insert your choice] stupid, wrong, flagrantly wrong, annoying, ridiculous, moronic, idiotic, neurotic, possibly insane post by someone, there's an app for that... no wait! Its not an app, its a thread within the forum. Go visit (and possibly check yourself into) The Lectern Lounge, and rant about posts that irritate you to your heart's content.
This is not the place to prove that we know more than someone else, it is a help and support forum. There isn't another one like it. Anywhere.
If someone has been posting that does not listen to reason, resort to either ignoring their posts or by private messaging them. (and then head on over to the LL)
Please, please please, remember that tact is a quality that should be highly prized on a public forum. If you think another forum member is wrong about something, the way to continue the conversation, if tact is not your forte, is via a private message. No one is perfect, and not only does everyone make mistakes, but everyone has the occasional bad day.
We have members here who devote so much of their time, and really give of themselves, hence, it follows that they also have learned through their participation here, in addition to their own personal life experience. So, if you're new, and a veteran member takes the time to respond to what you wrote, it will benefit everyone if you are able to grasp this fact. There is much collective wisdom here if you'll only listen.
Remember that new people may very well need help navigating the forum. Some folks are internet and computer savvy, others are not. So, give them the benefit of the doubt, pointing out ideas for self help such as the search function is even more effective if the person knows what the search function actually is. Also, many people may not notice that there are suggestions for "similar threads" at the bottom of last post on each page of the thread. Helping newcomers find a way to research helps everybody.
If an advertisement pops in as a new thread, or within an existing one, use the exclamation icon (click on it) to report it, rather than responding to the spammer, or charlatan directly.
