WinSend 2000 is Instant Messaging software designed for the business environment. WinSend 2000 operates as a peer to peer messaging solution. This means there is no server required to send messages from one system to another. Each individual system holds it's own contact information about the users you need to keep in touch with. You can use WinSend 2000's file transfer feature to transfer files from one system to another to share meeting information and documents. WinSend 2000 has a conference feature that allows any system to hold a conference and invite users to join in.
