SendGenie offers simple drag and drop file sharing for Windows and Mac
SendGenie also supports contact groups, so you can build a list for your department at work, your family, or your clan mates for easy mass sharing. You can also send clipboard contents -- like screenshots -- by tapping the Paste button in the main window and naming your clip. Once uploaded, your contacts will receive an email with a link to a page from where they can download your files. Friends running SendGenie on their desktop can choose to automatically receive files you send -- they'll appear in Documents\Me SendGenie\Your Email Address\Inbox\.
The app can optionally auto-resize photos you share, but there are no settings you can tweak. We'd like to see that option added before the final release, but SendGenie is still a very slick, easy-to-use desktop app for sharing files with your contacts.
