Integration between WPMU Dev Plugins

Hi,

I saw lots of professional plugins being offered by WPMU Dev. I plan to use many of them on a single site ( WP 3.8.1 ).

The WPMU Dev Plugins that really interest me are Forums, Membership, Directory, Classifieds, In-Post Ads, MarketPress E-Commerce, E-Newsletters, Events, Appointments, WIKI, Slide-In and Chat.

My target users are a closed community where we would like to deal only among us and not the public. Some sort of B2B but without using any payment gateway. ( All members will have to process whatever payments between them and between us – MANUALLY & PHYSICALLY. ).

When we really want to offer anything to the public, it would only be to promote products we selected from among the community members. Still all payments will be processed manually and no payment gateways.

We need a single sign-on for each member when accessing all functions each member has rights to. For example, if a member is already a registered user, they are automatically subscribed to Forums, Directory, Membership, Events, Newsletters and other functions.

Each member will also be able to manage their own profiles including personal details from a single interface.

Please advice.
