Thanks for the answer flazepe and luigi, one service that I like on heliohost is the free remote access of postgresql server, So I think I will stay, but I still thinking about that domain either, If I can solve that, so in heliohost server, maybe I just can host postgres server. So it can release some space for another user. I see that disk storage on heliohost almost full too, I cannot imagine if ricky will also down too.
