WordPress chat plugin installation:

Step 1: Download the plugin.
Step 2: Unzip it and put the Chatopica folder in your WordPress plugin directory:

(/[wordpress directory]/wp-content/plugins/chatopica/)

If your theme does not support widgets you can use a tag directly in your theme template. For example, if you wanted to put the widget on your sidebar you would open your theme's sidebar template and add the following tag at the location where you want the widget to appear:

<?php chatopica_widget(); ?>

You can configure its display by sending the tag width and height parameters. For example:

<?php chatopica_widget("100%", 500, "ffffff"); ?>

The above code would render the widget at 100% of its container, with a height of 500 pixels and a white background.
