This post aims at explaining how the micropost feature works.
Microblog allows the user to create short (400 characters or less, 140
for twitter posts) status messages that are then displayed in their
followers¿ activities feeds.
The user can also send directed messages using @, and tag the message using #.
The microblog widget also appears in the activities feed on people¿s
profile pages - if a message is entered here it is a ¿wall post¿ to that
person, in which case it shows up in the wall owner activities feed and
the wall owner¿s followers¿ activities feeds.
Users also have the option of posting to twitter. In addition, twitter
is polled for a admin configured hashtag and pulls in tweets with that
hash as microblogs.
Format
User mentions
Users from the personal address book can be mentioned in a micropost.
Mentioning a user will cause the micropost to appear in the mentioned
user's watch list. Mentions in the WebEx Social web client look like: @John Doe. This is represented by the following string:
@[uid, fullname, profileUrl] where:
uid is an integer and a valid userid
fullname is a string
profileUrl is a string
When the client submits a micropost with a user mention, the server
will discard and regenerate everything after the userid. So you can send
only @ and it should work.
Hashtags
Hashtags are a way to tag a micropost within the content like twitter
does. Unlike twitter multi word tags are supported although not exposed
at the day of this writing. Hashtags in the WebEx Social web client look like: #word1 word2. This is represented by the following string:
#["word1 word2"]
Links
Urls entered by the user are converted to links through a regexp by John Gruber. They are stored on the server using John Gruber's Markdown syntax. For instance, if the user types www.cisco.com the editor will convert that to a link to http://www.cisco.com which will be represented by:
(www.cisco.com)[http://www.cisco.com]

Rod - It is not supported out of box.
Partner was using an ACE like switch to terminate SSL. It simply converts HTTP to HTTPS.
With some external components, it can be made to work.
Hope that helps. Thanks for participating in the Forum!!
