I would like to submit this long overdue recommendation for Geraint, Tony & their team for the excellent support that they have given me. I have run Jevents on several different sites now, with different versions of Joomla and Jevents. Each site has had its own challenges. Geraint & colleagues have provided excellent support via my Silver level membership and have very patiently walked me through resolving my challenges. For those that I couldn't solve, they went in and solved it for me.
The product is free, the service costs a little but is worth every penny.
