Hi Guys,
Sagar here from techjoomla team. In our product jticketing We allow easysocial users to create paid events..JTicketing achieves this by allowing to create ticket types while creating event.
We don't allow users to Attend event until they purchase ticket from jticketing.
We just need joomla plugin trigger for this in this we will print book ticket option and ability to hide Attend/not attend
