it would be very cool to implement a right-click function where a user can ignore or query an other user.
Or just an option to double-click a user for opening a query window.
If someone can give me a tip where I have to search in the source-code I can try it by myself.
Double clicking is a good idea but I think I will go about this a message icon instead.
Message icon should be also a good idea. If I can help please let me know.
There's a lot of free icons out there you can use for open source projects like:
We probably just want to use Glyphicons included in the Bootstrap. E.g. icon-comment or even better icon-envelope. See: http://getbootstrap.com/2.3.2/base-css.html#icons
