Hi Jillaine,
As you may have seen, this comes up right above the "More information for the question" section when you're asking a Genealogy Help question:
For any family history question. If it's about a person with a WikiTree profile include the ID. If you're the manager, make sure the Privacy Level is as open as possible and contains as much as you know. If there's no profile yet, include what you know in the details of the question, esp. birth/death dates and locations, as well as any relevant URLs, where you have looked, what you're trying to find out, etc. The more you add, the more others can help. Do not ask about living people.
I don't know why more people don't include the necessary information.
Some people just never read directions and never will. For some people, maybe they'll read directions if there are just a few of them. Cutting down the above could help.
It could be that this only comes up when you're in the Genealogy Help category. It doesn't come up until you select that category. That could explain some of it.
