I've seen some venues away from they real place on Foursquare. (2-3 km away actually) Is there a way to correct these positions without claiming the venues? (Preferably from the web interface)
Misplaced venue in Foursquare

After some search I've found my answer.Foursquare support says that it is possible to edit venues on the web but to do that you have to be a superuser, the mayor or the one who added that venue.
