If you're trying to find a free and effective way to interact with your friends on Facebook or MySpace, then iSocial is one great application worth checking out. It's a free web based application that allows you to access your friend's list, create and join groups, play games, email other people and much more. It's a desktop-based application, which means it requires Mac compatibility and is available for download from the iSocial website.
The application isn't difficult to use - after downloading and installing onto your Mac computer, simply open iSocial on your Mac browser and sign up for an account. You'll be asked to provide your name, email address and any contact details that you'd like the application to send you messages too (so if you don't have iSocial you'll need to create a free account). After doing that, iSocial will ask you to select a category from a drop down menu, and in case you don't want to use the "general" option iSocial will also allow you to select just "friends". After that, you'll be able to search for other users just as you would on the social networking sites themselves, as well as browsing groups, seeing what groups your friends are in and sending and receiving emails.
It's very easy to use, and you'll only need to know a few details about your Mac computer in order to start using iSocial. Although this software requires Macs to function, it's available for free download from the iSocial website, so you don't have to worry about any cost at all. You can also use it from your Mac web browser, if you'd prefer. If you're wondering whether it works on the iPhone or iPod Touch, then the answer is yes. However, this software also supports those devices as well, so if you have one of them then it might be worth getting the iPod version of the application instead to use it on the iPhone and iPod Touch.
