I have been meaning to mention this but keep forgetting. If you wish to receive email from other members here, you must enable that option in your UserCP. It is set to "NO" by default. You need to click on UserCP in the menu bar, then click on "Options" and then check the box "receive email from other members". We use secure emailing here so by checking that option, you are NOT actually giving anybody your email address, it only enables email through the forum mail here.
Thanks
