Hi TTBit,
You called this "beta testing" so I want to give you a test report. I'm a noob with these coin clients so feel free to tell me to check the nut behind the keyboard. That said, here is what I see on my end.

1) Dividend Rippler
https://www.dividendrippler.com/account?_=rHUipvsbBKagmU5qxFYCVfRoHKkBaYztm2
Your site shows "failed payments". You said above that those can be ignored.

2) BitCoin
I'm using Electrum 1.7.3 but it shows that I have a zero balance.
BlockExplorer report my address as "Never seen"

3) LiteCoin
My LiteCoin client is still syncing the block chain, so I can't take its opinion as authoritative.
However, the litecoin explorer reports "Address not seen on the network."

4) TerraCoin
Notice that on DividendRippler I didn't configure a TRC account. (I'm on a Mac and I couldn't immediately find a Mac client.)
https://www.dividendrippler.com/account?_=rHUipvsbBKagmU5qxFYCVfRoHKkBaYztm2
However, your system attempted to send me TRC anyway.
THIS MIGHT BE A BUG. I'm not sure where those TRC would go if successful?

Anyway, that's my report. I hope it is helpful!
