Custom Module and core "hack" on JomSocial

We need some custom work done to the DISCUSSIONS inside the jomsocial groups. What we want is: * The threadstarter / discussioncreator to make a selection from a field called "Show on frontpage" which enables a custom module to fetch the discussion with the images that the discussioncreator uses in the discussion and the text etc written, like an article, but linking back to the discussion. * A second field: "Make sticky topic" enabling the discussion to be locked on top of other discussionthreads regardless if the other discussions have been created / edited at a later time. We also want you to create the module which we want to show the discussions which the authors have selected to be shown on the frontpage. This will display the discussions like a "newsarticle" setup with the image and some text..then linking to the full discussion thread. For the module we want the following backend options: * Choose number of "discussions" to be shown on the frontpage
