I personally re-upload to the gallery backup copies of any build or sim I'm using regularly. This is because each game file has a completely separate library, and I play several different games, _and_ I've lost two game files in the past. I learned the importance of multiple backup copies the hard way! Since I modify sims and builds, ths means I'm posting backups that are only a little if fervent from the originals. I always label them "backup copy", though, and they don't get downloaded much because they usually have cc in them.
