That's what I love about this community... so many willing to help!
(Sorry about the delayed reply; came down with a cold last night... wash your mouse after you finish reading this forum...)
Audioprobe, that's an amazing & generous offer... how could I say no? (How can you afford to do that?) Could you e-mail me at postmaster at blacklightradio dot com with details?
John, in fact my provider recommended the same thing, although they recommended 10 hours. If I'm able to hook up with Audioprobe, maybe I won't need to shorten listening times... if I fill THAT up (or when he wants his bandwidth back) I make go to that 4.5 hr limit you're talking about.
What I didn't like was that it started to connect... then stopped. It looked like we weren't on the air at all. Why come back to a dead station? At least, "please try again" gives them reason to believe they can hear it later. Not ideal, I know, but I'm finding it challenging adjusting to this sudden burst in popularity. 
AJ, thank you SO much for your offer of help. Once I get things squared away with Audioprobe, I'll e-mail you the info. I appreciate it so much!
(BTW, I feel like I could CREATE the playlists just fine, I just can't figure out how to get them to LoudCity... do I upload the playlists to my website, then put in the address to the playlist as the address of my server here at LoudCity? I'm obviously a little confused...)
Thank you again, everyone!!!
