 Imagine you have two ESP Easy modules, ESP#1 and ESP#2
 In the Rules section of ESP#1 you have this:
 
 .. code-block:: none
 
  on demoEvent do

 * ``SendToHTTP`` can now also be called with a full URL starting with ``http://``, so no longer the host, port and uri have to be separated. (it is still possible of course)
-* HTTP return value will be made available as event to be evaluated in the rules. Example event: ``http#hostname=404``
+* HTTP return value will be made available as **event** to be evaluated in the rules. Example event: ``http#hostname=404``
 * Calls made to a HTTP server can now also follow redirects. (GET and HEAD calls only) This has to be enabled in Tools->Advanced page.
 * Host name can contain user credentials. For example: ``http://username:pass@hostname:portnr/foo.html``
 * HTTP user credentials now can handle Basic Auth and Digest Auth.
