How do you pronounce "jellifi"? Jellify? Jellifee? Jellifih?
Was the original idea for it to be http://jellifi.sh, but they changed their minds and went with jellifi.com?
This is something they should figure out - if I tell someone "just go to jellifi.com" there's a decent chance they won't know how to spell it. So perhaps look into making the name more obviously spellable (jellify.com), extend to jellyfish.com, grab all the alternate domains, or work hard on your SEO so even misspelling it still nets you the right site. :)
