Hello everybody,

I'm trying to develop a plugin for roundcube, that integrates a weekly calendar [1]. The plugin need an external calendar server by the caldav protocol (davical,darwin calendar server, etc.)

Actually, I successfully detect invitation messages using the message load hook, however, I'm stuck with what I need to do next:

* Completely

modify message presentation, to display the message as an invitation, and include a text area and some buttons: accept, decline, etc. * Accept invitation, by executing some server side code. I cannot do it using Javascript/Ajax, because the calendar server is on another server.

Can anyone help me to start and tell me which hooks I have to use, and how to use them for these tasks ?

Thanks.
