Good point if that's an issue. Not sure how that works, cloud pricing etc. It's gotta be pretty cheap though. Another 10 zigabytes for $1/month? I dunno. Beats me.
You can upload mp3 files, but they aren't automatically playable (at least while viewing an EliteTrader page in chrome). e.g., see the attached a_man_with_money.mp3
I looked at the acceptable upload sites for ET, Jiffyshare seems to be the best. It's just click and play.
We aren't a music streaming service so just upload to Soundcloud and then post the link. So easy. So straightforward.
Soundcloud is where every song that has ever been created in the history of humanity has been uploaded to. I'm sorry you've never heard of it.
