In the ACP->vBSlider->Options, select either the FORUM options or CMS options. Inside of those options, you can select how many of each type of content you want to show. Since you are showing forum threads, you probably still have the default of the most recent 5 forum posts selected. If you just want to show your own messages, set the CMS, Forum, and Blog counts to 0, and custom content to some value (5?).
