If you are looking to get the word out on an event, or if you are a community oriented person, a website can be the perfect and affordable way to get your message out to a huge internet audience.
I created the site www.firstfridaydenton.com to highlight, and organize participants around an event I started in Denton, Texas. First Friday Denton is a monthly organized event that I thought would benefit from wordpress’ ease of use by all the participants.
Now, I receive monthly updates about special events on First Friday and post them as they come in. There are links to participating businesses, and pages that have permanent information on these businesses – broken down into business categories. There’s even a google map with pins so that someone not familiar with the town can find their way round.
And if you’re really interested in changing your site for seasonal events, just change wordpress themes
