Is there a mod/way to make it so people need a certain amount of post before sending a PM? Also is there a way to make a certain forum require the first post to have a template? When someone makes a thread i want it to have a template for that first poster.
A solution for the 1. part of your question (without any plugins):
1. Create a group for new users (without PM permission)
2. Create a second group, with PM permission (or use the "Registered group")
3. Set the default group for registered users to the group without PM permission.
4. Create a Group Promotion (ACP: Users & Groups -> Group Promotions -> Add New Promotion)
5. Choose your min. "Post Count" (e.g. Post Count Greater than 5)
6. Select the "New User Group" (e.g. "Registered", with PM permission)
Now, the new users (0 Posts) are in group #1, without PM permission.
After the 5. Post, they will switched to group #2, with PM permission.
