[beta 3] Cannot tag people on wall post

As stated above, when you tag someone on a wall post ( @Adam Howard ) is does not work.

Quote from Black Rider

Comments (even wall posts are just comments) use just a rudimental version of features. Just smilies and URLs will be displayed – and text, of course – but no other code format.

Would be helpful to tag someone else to a wall post. Let us assume I was talking about you, Black Rider on let's say for example on Alexander Ebert wall. Rather than having to send your a PM to clue you in, it would be a lot easier to tag you and draw your attention
