The themes are nice but somewhat outdated. Why not use the designer who did your "freetrial" landing page? (see attached screenshot) A few nice landing pages like your very own landing page would get me more excited to join. Please send samples if this gets legs under it. Thanks.
I agree. The layouts are at least 10 years old.
One of the selling points is the web builder. Having to hire a custom theme maker defeats the advantage.
