hi, sorry for my bad english. I have a big problem with the Event Newsletter Mailer. When i go to send the newsletter i see this error: "Error: Newsletter has no subscribers."

but i have a lot of subscribers...

thank you for your work! Please answer me

PS: i use joomla 1.5 and php 5

The likely problem is that people haven't actually subscribed to the mailer. Just having registered users does not make them subscribers. People on the website must subscribe themselves; right now there is no
way for an admin to add subscribers. That feature may be added in a future version of the component. For people to be "subscribed" they will need to subscribe themselves from the frontend (by using the module). Hope that helps.
