Hi, everybody.
i would like to present to you this little snippet. Let’s say 0.01 version
code in attachment of this post. Instructions is very simple:
1. ugzip archive
2. create new snippet in Manager interface, call it however you like

3. copy/past in new snippet code from file opossum_who_is_online_snippet.php
4. edit some variables in code (for change output layout)
5. call snippet w/o cache. that is [!your_snippet_cool_name!]
6. enjoy!
As for me i plan to add some feature: like full chunk support and more placeholders (there i need feedback from you.)
Good luck!
