Online text ... like we have here

How do I go about putting the glowing Online text under the username like we have here? I assume it's just something simple to be added in postbit, but I'm stupid :D

Search in the forum, I posted if at least 20 times before. :)
(hint: take a look at postbit_online/offline ;))
