Hey, am really not sure how this works at all and as for the prices in subscription cheapest seems to be $2.99 but on main site it says $0.99
This is very complicated! I want to use pay per traffic but there is no guide or any form of tutorial, user interface extremely poor!
for instance why do I need buy credit for pay per traffic??
Sorry for this problem. 
I’d added it manually so for a while you can test with all mudfish nodes.
And I totally agree with you that documents are really poor so if you have any question, please let me know.
> for instance why do I need buy credit for pay per traffic?
It’s caused by Mudfish system design because there is no any kind of auto-billing system based on credit card. It means each mudfish user requires a minimum mudfish credit to use service.
ㅠ.ㅠ 음… 선택하신 중계 서버의 연결 문제일 수 도 있어 보이는데요 혹시 다른 중계 서버로 변경하여 시도해 보셔도 같은 증상인지 한번 확인 부탁드립니다.
