I can't track down the proper message mentioning the hashtag, but it may be useful to make sure UFO Investigators (or some other interesting entity) doesn't already make use of #\UFOI to an extent it would be a problem. I think #UFI would be much less a problem. I wouldn't know. Checking may be useful.

The issue is that UFI isnt availible as a website, UFoI.org however we own.
