On the 6th December 2012, I posted my first pieces on CBCH. I tried the first upload as a WAV file, and nothing happened, as we all know by now. I then tried the time-honoured mp3 upload, and was in business. Subsequent uploads have been mp3s. All good.
Imagine my surprise when I checked my page yesterday and found two instances of my very first uploaded piece! Both showed the same date. The wording in the description of the "new" one was slightly different. I believe that this is the one I tried to upload as a WAV file. If so, it has been hanging around in cyber limbo before its mysterious manifestation. I deleted it in the interests of sanity.
If anyone else has a plausible explanation, I'd like to hear it. As I've said before, always something new on CBCH!
