I’ve started a website for local Miata enthusiasts: Vancouver Miatas.
I used Joomla to run it, and I was amazed at how easy it is to set up a website. There are a ton of plug-ins (called components, modules, or mambots depending on what they do) available to do whatever you want. Events calendars, galleries, classifieds, or anything else you want in a website. Sometimes the quality isn’t that great but there are a lot of nice packages out there. You just need to try them out.
