I didn't realize for more than ten years, but, i had backed up my Jazz2 folder onto a CD, and it seems to have quite many CTF and Battle levels, as well as a huge amount of levels within the Cache folder, most of which are from 2000 and earlier! I am sure there are some lost gems, I will be looking through and hopefully posting some of them here very soon (especially after checking to see if they are in the J2O archive or not!)
