This plugin is geared toward bands and musicians to manage and display a 
calendar of their gigs within WordPress. It’s meant to be as easy as possible 
for both the musician and the fan. It even manages venue data complete 
with mapping and ticket links.
<h3>Compatibility notes</h3>
= Browser = 
This plugin’s administration pages are currently only supported fully by the 
Firefox and Safari browsers. When I am approaching version 1.0, I plan to 
develop full support for IE7 and Opera. If you would like to know more about 
my decision to focus on Firefox and Safari, feel free to get in touch with me.
<h4>WordPress</h4>
If you are using a WordPress version less than 2.3, you may need to create the 
database tables manually. You can find the SQL in tables.sql. Get in touch with 
me if you need help doing that. You might also want to consider updating to the 
most recent version of WordPress.
<h4>MySQL</h4>
If you are using a MySQL version less than 4.1, filtering the gig posts from 
your normal blog entries will be disabled. You will need to filter those based 
on the category you select in the settings page using another plugin. I suggest 
the Advanced Category Excluder (https://wordpress.org/extend/plugins/advanced-category-excluder/) plugin.

WordPress Events gives you a simple interface for adding events to your site and displays them in a beautiful calendar with pop up details.
Simply add events in an interface you are already used to and display your calendar by adding the shortcode <code>[calendar]</code> to any page of post!
New in 0.2 !
Multiple user calendars! Allow individual users to have their own calendar and display different calendars by specifying a user id in the shortcode. For example [calendar user=2] will display the calendar for the user with an ID of 2.
Built in sharing generates tiny urls that when linked to opens the shared event in a pop up just as if the user had clicked on it.
Google maps integration allows you to add a map of the venue.
