Redmine

It is nice to have some like when i type @user in any of redmine wiki areas (wiki/issue/comment...) user got a notification.

1. And if in issue or issue comment, user got automatically add to watcher list.
2. And even more, when I type @ i got a auto complete user list.

Unfortunately, when I typing this, i found that @ sign is current used in the Wiki Syntax.

• Maybe + or at least user: could be the fine.
• Or Maybe @ can enabled in Markdown Syntax. (I found that Markdown will add in 2.5.0 )
