Our venue has multiple spaces with simultaneous events, and Ohanah has been an invaluable addition to our website. We use a responsive template (Joomla 2.5 w Gantry) and Ohanah integrates and displays great. Simple dashboard, easy to use. I was able to customize the calendar CSS to match our site colors by reading the Ohanah support page. When I encountered a problem with my template CSS creating a letter-shadow that made the Ohanah calendar display appear blurred in one page, Ohanah support resolved the issue within 48 hours of my initial request. We haven't used the pay or registration feature, but the rest of the features have worked great. I have students who enter the events, and I can easily show them how to get entering within 15 minutes of training. Glad I found it!
