This is an issue I wish ACOM would address. I have quite a few interviews I've done in the past 30 years, and I would love to share them with others by uploading them to my tree. Until just recently, I recorded using a portable tape recorder, so I had to upload the tapes to my computer. I made them .wav files, and then converted them to .mp3 so I could email them. Andy's suggestion is a nice one, but I think ACOM just needs to make this a priority and allow for larger files to be uploaded.
