Go to your administration control panel --> User Permissions. Access your own permissions. Click on "advanced". You should see a column called "calendar." Make sure that the boxes are toggled to "on" for the forums in which you want to be able to make calendar posts.
I do have a calendar colum under advanced settings, but only on those sections of my forum, that is empty and without content.
Furthermore, a new topic is still just a new topic
This option, to make a topic in the calendar or not, is this, before i push submit or after?
If before is it like making a poll, announcement etc?
Dio2, is there any way you can be more specific based on the info from above?
