@Raf - i'm not admin, but generally, it's completely normal that places are not marked as located immediately. Additionally, usually it isn' sufficient just to claim a certain location; see "Using description":
"Please provide further explanations in the comments to the right. You are able to insert links to prove your suggestion, e.g. with Google Street View. "
So, it may (!) make the admin's work easier by offering proof for a certain location's claim. Of courese, this isn't easy for places not publicly accessible, but maybe there are some indoor pics online available from a reliable source.
@Admin : is there any particular reason this is still marked "not yet located" while I located it 18 days ago?
I pinpinted this a week ago... Why is it still marked "not yet located"? Am I doing it wrong?
