We are _the_ event component for Joomla that offers the absolute most features at all - and the freedom and flexibility to change everything around to look like you want it to.
Using tags to create your own way of showing things, creating custom fields etc. is _not_ programming knowledge - you dont need to know a single line of php to completely customize your own event system / event portal page.
As for support - go visit the forums - i havent seen anyone answering forum threads in the same speed we do.
I give the review 1 out of 5 stars - because it fails to see that redEVENT is allready, by far, beyond what others offer - because redEVENT does not require programming skills - because we answer support threads on forum expetionally quickly.
The 1 star is for the documentation comment - yes the documentation is a tad behind as we implemented soo many new features - but after the next release which finishes the last step of redEVENT v2.x series features we will update it.
