reviving old Nexuiz maps

I don't know if anyone would be interested in playing some old school maps but i could take a look into updating some . Maps.nn does'n't seem to be hosting  the nexuiz maps anymore . Does anyone know  if there is a repository that still has them ? I just came back to the community after life has had me away ,and i saw Stone Castle on the servers . I updated that one years ago and thought this may be where i can start back again . other than that im going to brush up on some mapping tutorials and get back in the swing of things . I'm sure there are some new features to netradiant that have been added since I've been gone . Is there anything else new i may need to know about contributions to mapping or just in general ? Thanks guys , see you soon !
