Tagging someone is a great way to let them to see something that you have posted.

To tag someone, type the '@' sign and then start typing the persons name without adding a space. A drop down menu will appear. Choose the name of the person you want. It will be added and then you can continue your post.

If you still have problems then just message a moderator or leave a post here.

You learn something new every day. TJ is so much better than Tomatoville and I'm really glad that I found this place.

@MissS indeed a very useful feature!
