[@Inkarnate] Yes, having a player or two in on certain details is fine and can be well used. (Though I have had Co-Gm's go behind my back and tell things to other players that shouldn't be brought in yet.) That is one thing but that isn't what I am talking about in the slightest. 

I am speaking of people who are constantly questioning everything. "[i]Well what happens if I go here, or do this? [/i]" types, or [i]"Why did this NPC do that?"[/i]. Trying to metagame before they even post by getting information before hand so they can change what they are doing for the outcome they have plotted out in their mind instead of seeing where the RP takes them. Or worse yet, those that have been informed that everything they need to know is either IC or in the original OOC post and then they still prod for more. Even after the Gm has constantly told them, wait and see. 

With many Rps I don't run into this but in Mystery RP's I run into it constantly. They want clues to solve the puzzle without doing the work IC. For me, what's the point of joining a mystery RP just to constantly ask the Gm for solution on page 1 of the RP.
