PLease upload yourself your presentation by editing the corresponding entry of the agenda page;
Please note: individual uploads cannot exceed ~25 MB !!! unfortunately, the system does not tell it to you, it simply goes back (quickly) to the page viewer. Note also that attached file extensions have to match and be part of the list of uploadable files (of course .ppt and .pdf are OK, I think pptx do not - yet).
