You can store as many media files in the library as you like. Audio or video; whatever type and format you need to make avaiable to your people, you can upload and store in the CorpsData library.
Participation in your ensembles is going to require many documents. Permissions forms, how-to documents, music, choreography - you name it, you can store it in CorpsData.
You can set permissions on each item in the library down to the ensemble, section or position level. So you have complete control over who can access what. And of course you get an unimited amount of storage for your audio, video and text files with CorpsData.
