There are two excellent questions about beginner RPGs; one specifically calls for younger players, but the answers are very similar between the two. Is there a way to flag these for merging?
Merging questions is possible, but it takes a moderator (diamond by name) to do it.
A moderator can choose two questions. The "copy question" will get wiped and locked, and all of its answers and comments will be transferred over to the "original" question.
The typical way to handle this is: vote to close one of the questions as a duplicate, then flag it for moderator attention with a short message.
