I like the look of the website after visiting for the first time, here are a few things I wanted to point out.
1. I don't like the fact you have a donate button on your homepage along with the mention of it being for server costs, when people look for a host they hope they are financially stable and aren't going to disappear the next day. Having the donate button makes me wonder if you're going to struggle to pay the fees, even if it is a free host. Perhaps make it a little less obvious or add it to the members area.
2. The mailing list form is a little bit full on in your face, perhaps making it a little smaller, and possible have a customer review box there instead?
3. On the mailing form subject, the alignment gets messed up when visiting the client area (

Overall it's a lovely clean and modern design, it's not the choice of colours I would specifically go for but they seem to work well together either way.
Good luck with your hosting company.
