add multi day reservation, blocked (blackout) reservation and e-mail notification to working JONGman component for Joomla 2.5

I used the JONGman component for Joomla 1.5 for a long time. It's exactly what I need for a school website and room reservation. The component has been published as an Alpha version for Joomla 2.5 and I hired a freelancer who made the component work, but there are still some missing features which have not been implemented yet ... these functions don't seem to work. The follwowing functionality has to be added to the script : - multi reservation (already implemented and started, but not yet finished ... does not work for the moment) - blackout reservation (blocked time slots) for super administrator (just like in the Joomla 1.5 JONGman component) - e-mail notification (confirmation) for reservations These functions already work for 100% in the JONGman component for Joomla 1.5, but not in the Alpha version for Joomla 2.5 You can find the JONGman project and download the 1.5 and 2.5 components here: [login to view URL] I will provide the modified component so that the other functions can be added. These 3 functions are the only functions which don't work for the moment in the Joomla 2.5 component. Have a look at the Joomla 1.5 version to have an idea of the work. Thank you!
