When I took over the Milwaukee Croatian Tamburitzans website it was originally created by someone else in Microsoft Front Page. We have gone through a few phases in this process, I started it with GoDaddy Website builder to keep something online fast and utilized another hosting option to include a calendar. Then moved to a CMS utilizing plugins to power the calendar. In addition to the website. I also authored the DVDs from Milwaukee Croatian Tamburitzans 2015 Concert that were given out to parents and alumni, as well as sold to general public. Since they are non-profit, I set them up with google apps for non-profits, and got them squared away with email marketing to spruce up their email notifications and work on phasing out what they can with snail mail.
Prior to moving to a CMS system, we initially has the website set up on a GoDaddy website builder program. This was the previous style, I had to at that time create an additional URL with a PHP/MySQL based calendar for events. The transition to CMS was to improve that type of functionality all in one.
