Forums / Cotonti / Support / Problem with registering

Hi
Like the title says i am having issues with registering on my site
It has been tested a few times but the user who registers doesnt receive an e-mail from my site
saying to activate their account with the following link
so I have to manually move the account from inactive to members
Is there a way to fix this?

btw I am using cotonti 0.0.5

Thanks
