First off, great extension, thanks for your effort.

I am having an issue with Emails being sent even though I have Do not send notification set under One Click Registration Comp settings.

I am using the component to allow people to easily signup for newsletters for the website, but didn't want to confuse them as to why they was receiving login information.

Any suggestions on how to prevent the emails from being sent out would be very appreciated.

On some server like WAMP or XAMP servers the component might behave buggy. Also it think joomla 1.7 has some WAMP/XAMP issue's. You might want to try configuring the component at the menu item.

Go to the menulink to OCR in the Menu manager of the joomla backend. When you are editing the menulink there you can see the component parameter box to the right.

Click on the component parametersbox and you will see the settings. These settings are the same as in the general components parameters but you can assign different parameters per menulink. This will make it possible to run multiple instances of a component but with different settings.

Try configuring the component there and check if this works for you.
I hope this helps, Kim
