Book Excerpt: JDS Instant Messenger (IM)
Instant Messenger offers fine-grained control over whom you permit to contact you. This is a very important feature, because instant messaging can seriously disrupt your attention on the desktop. Without Privacy Control, instant messaging is useful only in personal or social contexts and can scarcely be used in business settings. It also allows users to maintain large Buddy Lists, while permitting only a few chosen individuals to make incoming contact.
To control privacy, go from your Buddy List to Tools > Privacy, where the window offers a variety of choices via a drop-down list. (Figure 10.) Among Privacy settings, the following choices are available:
Allow all users to contact me
Allow only the users on my buddy list
Allow only the users below
Block all users
Block the users below
JDS Instant Messenger is in the beginning stages of offering the ability to transfer files over an instant messaging session. File transfer is supported to varying degrees by the different instant messaging services and protocols.
Generally, you can send and receive files that are less than 1 MB in size; however, protocol support must exist at both ends of a file transfer for success. Trial-and-error is a good way to see whether file transfer works for you with certain colleagues. Support may sometimes be present but undocumented.
