At the bottom of my sidebar I've added some buttons that indicate my online status on MSN Messenger, AOL Instant Messenger, and Yahoo Messenger. I'm using a service called Online Status Indicator, which generates the code for me after I enter in my screen names. Then all I have to do is put the codes into my template and I'm set. If you post on message boards there's also codes for your signature. Now you can find out if I'm online while navigating the site and send me a message. I recommend this service instead of using the ones provided by the IM client. It's simple, clean, and easier using OSI.
