Note guys I'm trying to get our developer to bulk remover all the posts.
To explain what the issue is, the original developer who made this page used custom coding for everything (instead of just taking the base code). So our current developers cannot install any plugs or make any changes to the discussions page as it just crashes the whole site. We're looking into alternative solutions but that's why its taking some time ... Even something like a feature to remove all posts from a user is not possible right now.
But rest assured I'm really trying to get things going it can be fixed asap.
