Tagging a forums member
If you want to respond to a forums member and you want them to be notified of your response then you need to tag them. In order to tag someone you type the @ symbol and start typing their username. A drop down box will appear below and you select their name when it comes up. It should appear in blue like this eg. @tyme

If it comes up in blue and their name is spelt correctly then they will get a notification and next time they are online they can check your message.
