Please tell me you have these shared with the world via a website somewhere? It would be great to have access to your archive of user-created levels.
lvlworld.com - Curated, the polished and more playable end of the spectrum
en.ws.q3df.org (Worldspawn Archive) - Mostly focused on defrag (trick jumping) maps but has a lot for the standard game mixed in.
Excessive Plus's FTP server at ftp.excessiveplus.net
efservers.com/maps.php Elite Force Map Search. Has a lot of regular Q3 content buried amongst the Elite Force stuff.
