I like how easy it was for me as an instructor/parent volunteer at my son's dojo (dojang) in California when we moved from Colorado last year - just logged into their site once upon arrival here so far this spring semester; they had everything set up right away without any problems whatsover!! Their customer service has been awesome too. The only thing about them now seems very dated looking compared to other platforms out there such as ClassDoJo etc.. but then again maybe not since those are more geared towards teachers / parents who want greater control over scheduling classes & teaching materials online vs relying solely off instructors being available during class hours? We're using CDJO mainly because 1.) They offer great benefits packages including health insurance through COBRA if needed 2.). A bit easier than managing student rosters by myself 3). Great community support 4), better platform overall 5.),.
