I would like to put this in the forumhome_forumbit_level1_nopost template so that it can be on top of one of my forums. When I insert the code nothing appears.
That is because this is not written for that area of Photopost
You would have to try and edit the plugin and move the plugin location to wherever controls that template area. Maybe forum_display etc but I dont know honestly since I have never tried it
Linear Mode
