Create Thread From Forum Home is the template modification, now TMS addon that allows members create a new thread from the forum listing. This resource is slightly different from the original one I posted because I've substituted the 'Post Topic' button for a 'Create Thread' button. You can see a working demo of this addon at www.8thos.com/board
Perquisite: Must have the Template Modification System installed.
Directions: Upload the contents of the Upload folder to your forum root. Install the addon. Feel free to use your own button by including it in the styles/8thos/ folder and changing the CSS in your theme's Template Modification Edits settings. Use conditionals to prevent the button from being seen by guests.
