Emoticons
Emoticons have replaced words and expressed human emotions wherever possible. The otherwise dull and boring conversation has now become far more lively and peppy, thanks to emoticons. Now you will find that most online conversations have more of emoticons and less of words. Ever since the emoticons replaced the text characters, they have undergone huge changes. While there were just the few basic emoticons earlier, now there are separate menus in most email and chat clients. This menu activates a pop up from which you can select from amongst hundreds of emoticons.Categories
Now emoticons are no longer restricted to human expressions. Animals, objects, music have all made an appearance as emoticons. For example an emoticon of a guitar may suggest that you have guitar a class to attend to. There are pet emoticons as well which are extremely popular. Now you can show what dog you own with an emoticon. There characters differ from each breed of dog to the other. You can find a list of these characters on many on line websites. Smileycentral.com is a good website to begin with. These guys have more than 10000 emoticons online. Now, that is a huge database. Each category has more than thousands of Emoticons that you can download and use in your mail and chat programs. But this is ad supported software and might require you to install their software before you can get access to their super animated emoticons.
Freeware
You can also get a lot of these programs for free. But the best thing to do is use the emoticons supported by your mail client or chat client rather than having to download anything. In fact you will find that these are more than enough and have most of the emotions covered.
