It seems like Allyou is not being developed anymore, the templates are few and old, there's no ecommerce and it's way to expensive at $20/month for 10 Gb of storage. There are also other issues, like the lack of forms (or really any kind of widgets), for which they suggest using Wufoo (third party).
I can't really see a compelling reason to use Allyou when there are so many better alternatives feature and price-wise.
