I don't know my SMTP settings. Can I still install Jumptree Project?

Yes. You can skip the SMTP settings during setup.

But this means Jumptree Project will not be able to send out emails when these actions are performed:

1. Creating a new user
2. Creating and updating tasks
3. Creating and updating discussions
4. Email task reminders
5. Mass email notifications

Of course you can always edit the SMTP settings later.
