How to use Fluther most effectively to get the most reliable answers?

Post a question in general and be very specific.

Be specific
Read the room
Know your audience
Try not to chuckle…out loud.

@LuiJavur777, this may not be the place to get answers from professionals in your field. It’s a small community, as much social as otherwise. If a profession is represented at all, there may not be more than one or two of its members here.

I think the best advice overall is to watch the site for a few days and get a feel for the culture. Read the guidelines. And then do as @KNOWITALL says: post a question under the General heading, and use the Details section to specify clearly what it is you want to know.
