What is a reliable Instant Messaging Service in an office for both MAC and PC?

I'm looking into installing an instant messenger on 5 computers here at the office so that we can use it for communications. I need one that works on both MAC and PC and that is reliable. Preferably, I'd like one that doesn't have a real loud look to it. Just something simple that we can send simple text messages with.

I would suggest using Exodus... you can set it up by creating an intranet, so only the 5 computers can talk to each other... it takes out the hassel of outside communications via messanger and any possible virus that could potentially be brought in... if your looking for something that doesn't require any set up try.. AIM, or Yahoo! Messenger... there is also MSN Messenger and Windows Messenger... Good Luck

I can help you with this.

You can use the inbuilt s/w named iChat which has the option of chatting between mac and windows PC's if you have a AIM id.

With a AIM Id you can login to the iChat s/w. At the same time on a PC you can install AIM and login there as well. You'll very well be able to communicate from Mac to the PC without installing any new s/w or changing any settings.

Choose iChat > Preferences, then click the Accounts icon. If you're using an AIM account, enter your screen name and password. Your password is added to your keychain so you don't have to type it every time you log in to AIM.

For AOL Instant Messenger accounts, enter your AIM screen name (for example, tclark3001) and password.

For Jabber accounts(GMAIL Account is a Jabber Account), enter your full Jabber ID (including the name of the server, for example tclark@gmail.com) and password. Also You can install Gtalk on your PC's to establish communication between the Mac and PC.

Hope this helps!!

Good Luck :-)
