Event Add Participants

[gallery666]

hi, after creating an event and joining as organiser, and selecting participants to invite by ticking their checkbox...
how do i then send the invitational emails?......

it says 'Checkbox status is saved automatically after marking'.....does that mean that once the box is checked then the email is sent?

i can send and receive emails though the the interface.....just not sending event emails....am i missing something?

thanks again, in advance
