Found a new annoying thing about Facebook Fanpages:

I'm not able to insert the adress correctly as I see it.
Facebook insists on having the adress I enter match their database.

Funny enough it allowed me to insert nonsense like:

wef
werf
wergt..

Which still shows up after I have edited the adress to something real,
which is still not matching the real adress of the place I made a fanpage for.

The people I made it for are happy about it though. :)
