Budget: Don't Know

Firstly, if you have applied for the previous requirement posted here, thank you .. we have now found our solution. We have a client that wants to set up a service where users can sign up to manage their life online. There is no requirement for the design side of things as we will do that. Users will want to : Sign up for and use email (webmail) Manage their contacts Make notes on a notepad (reminders perhaps) In future, the system will be expanded to include : Storage and retrieval of documents and other files Calendar These are two examples : http://www.jooce.com http://www.zoho.com Other requirements : Ability to drag items (drag contacts to the email module for example) to the main screen Reason : the eventual use of this will be for PC Tablet users
