Speaker Self-assignment in Frontend

Hi,

I really would like a way to enable my speakers to assign themselves for an event in the frontend. They have the rights to edit the events, but they do not see the Speaker-Tab in the Edit-Form.
A way to edit the custom fields for an event in the Frontend (same problem as above- the Extra-Information-Tab is invisible) would be an alternative for my usecase but I would prefer the first solution.

Regard Thomas

To whom it may concern: The feature allready exists but only works for non-recurring events.
To make it work for recurring events, I changed the file \plugins\eventbooking\speakers\speakers.php an deleted the lines 256-259 and changed line 219 to "$eventId = $row->id;"
