As a web developer, its always hard to find extensions that will work in a production environment without issues...ohanah is one of them! I've used it with many joomla versions, along with other modules and i've never experienced a problem or warning. The interface is clean, straightforward and full-featured, not to mention the fact that is easy to customize(though its hard to need an option which is not already there). The support of this module is fast and effective, if you ever need it... so its an excellent product (probably, the best event-management module for joomla) advised for anyone with event-management needs for joomla.
thanks for your nice review and kind words Simone, much appreciated! glad we made your life at work easier :-))
