Hello  everyone , I am part a  a team working on a cave data base project for those  cavers  travelling around  Europe  . The name is Grottocenter

There  is lots of  freely accessible information , including location  and rigging sheets.  There is a forum also to share information .  Have a look ,  you might  find it useful !!
