I often look for event ideas which are unconventional and out of the box. I found that Youtube is definitely a great resource for these kinds of tips. All you have to do is browse Youtube and do a search for "event tips" and you are going to see several hours worth of videos clips with lots of fantastic tips. The trouble is, who exactly has enough time to see them all? Thus I am on a continuous mission to gather some notes so as to save me and also hopefully other people some time.
