They opened a community for Lotusphere on Lotus Greenhouse. (Go HERE to access it! MUST REGISTER FOR LOTUS GREENHOUSE FIRST) In this community, there is an Ideation Blog where you can vote on what BOF’s you are interested in attending. What they also have is a link where you can submit new BOF ideas. (Some people have already submitted new good ideas.)
Deadline is in the next 2 days, so get your ideas in now!!!
