Well FengOffice sounds a little bit like a Chinese crunchy cake... Maybe with time i should get my mind to absorb this name but overall i don't like it.
From a commercial point of view it will be better some kind of short and effective name, like
woff
(web office)
inoffice (everytime in the office
)
YAWSO ( Yet Another Web Suite Office) the best!!!!
these are my small suggestions... a little hilarious but effective
