Hiya Hoverclub

Awesome mod, but doesn't seem to be sending out newsletters.
Using latest version of smf and mod.
Installed fine.
Using Fresh Looks theme.
All options selected fine, and able to preview, after suggested change in order to be visible.
20 have subscribed, through click box at top of forum page.
Checked all settings throughout admin section and can't see why it isn't sending out ... no errors showing in log.
Thanks, Cat
