User contacts allows your users to manage a list of contacts (names, addresses, email addresses) from their account page.
Note that the contacts are not user objects and are analogous to say an address book in Gmail.
Features
Flexible permissions, allow power users to view and manage contact lists for other users or limit it to per user management
Contact Importer intergration - allow your users to import their addresses from Gmail, Yahoo, Hotmail and other webmail services supported by Contact Importer and the OpenInviter Engine
Feeds integration - defines a processor for feeds allowing you to setup imports into your user contacts data. Comes with a preconfigured importer for importing from CSV
The user files module allows your users to upload files to the site without creating nodes.
Files uploaded are associated with the uploading user and private, even whilst the site is in public file mode.
The files themself reside in a folder that is not publicly readable (via .htaccess directives) whilst the module permits the owning user to view/download the files by rerouting urls via the private path (system/files) and then performing the appropriate permissions checks.
Analysis of uploaded images to identify color-spectrum
Requirements
The .htaccess directives only work with the Apache http server, ensuring the uploaded files are private on other servers is not supported (patches welcome).
