i have a silver membership and can publish up to 25 websites. as a consultant i have been designing some websites for clients but putting them on my account and therefore managing their websites for them. if i want to move a client off of my account, how can i do that? what i mena is, they want to control their site but i don't want to share my yola account login and password with them. they would need to purchase their own account. if they do, can the site i created for them be easily transferred? or would i need to rebuild the entire site on the new account?
