as you can see, the whole discussion was caused by a hosting problem with the preev.com site. Also, I buy preev.net because the previous owner did not set aside a measly sum for extending the domain and hosting. it is quite possible that the problem is not the amount of money.
Regarding development, ease of use is the main advantage, all additional complications with extra features will detract from the usefulness of the service. I think all users of preev service (or their alternative) know about CMC but for quick info, they prefer to use a simple page without redundant information.
