Well for guidelines on how to open the threads to mantain order would be:
to categorize the suggestions by what they are, for example open a battle suggestion to make a suggestion about the pvp system future Mpvp and anything battle related the user would like to suggest about. and so on opening other threads like jutsu, KG, elements, training exct then all the future posting would be posted in their correct category. A miscellaneous tread can also be opened for ideas involving other game-play features that dosent necessarily falls in a category.
can also be done backwards, if theres something implemented you dont like and would like remove say what it is and why should it be removed or if it is afecting game-play.
and as to how to suggest something would be better if user cut's straight to the point and say what he/she wants to be implemented in the game and also mention how would it benefit the game-play.
-if i miss anything feel free to add them, il appreciate it. since i was thinking when suggestion gets flamed it will take to much un-necesary space inside the treads making it difficult and annoying for an admin to read, tought the flaming is important to judge how ppl like the ideas.
