Do you have any problem with a trigger in your map? Do you have an idea for a spell and you want to see if it can be done with triggers? Then here's the place. Everything related to the Trigger editor and scripting can be discussed here.
Do you have any project related with Warcraft III modding? Here you can advertize it or create a general discussion about it. If your map in this section is finished and ready to play, you can request a map moderation by sending a PM to the any Resource Moderator.
