some advice please

Hello everyone,

My situation is probably not unique, but I simply don't know how to do it. Hopefully someone can help me out. I've installed the Free version (free service) on one site, and the Pro version(paid service) on another, as they both provide the same services and need the same sort of protection structure.

My sites are themed for Project Management, and I want to create Client Access Areas for my Clients, to store pertinent information, like quotes, invoices, images, documents, autocad drawings, etc. Each Client Folder can only be viewed by the applicable Client, so the other Clients can see or sign up to the other 'Projects'.

I would like to create a page, with all my projects listed. Then the applicable Client, selects his Project and signs up, etc. Once signed up, they have access to their info. No other information should show up in their Subscription Page.

How is this done! Is it easier just to create the username & password and mail them the ldetails & page link.

Here's an example of one designer folder in the project 'Longcheer':

./longcheer - main folder, which has the .htaccess & index.html
./longcheer/dibley - next folder
./longcheer/dibley/images - sub-folder
./longcheer/dibley/quotes - sub-folder
./longcheer/dibley/autocad - sub-folder
./longcheer/andrews - next folder

Does there have to be an index.html in every sub-folder?

Thanks in advance,

Greg
