Loads more easter eggs are on the forum,another one of them, similar post count thing(which no one has achieved yet)
ask shorena for details seems if you have 100,000+ posts it shows your post count as "I'm a geek!!!!". One more that I know is put your birthdate as today(any year) and see what happens.
Edit : Some bonus features not necessarily easter eggs:
Some hidden BBcodes:
Like /me in IRC * user test
* NLNico test
[me=user] test[/me]
