Click on the picture, and look at the the things, underlined in red.

* Note : On the picture, it's written : last Activity : 1 Day ago. When I posted this message, it was still 1 Day. But now (29 August 2010), 15:35 (about), the "Last Activity" is dated "2 Days Ago".
That means, that 2bartz was still on Ragezone the 27th August 2010, 15:35...
Yea, it is the same 2bartz. it's the admin of this server.
More proofs ?
Here, the link of the post (still on Ragezone, THE forum of MMORPG's Private servers development) whose 2bartz used to create Giolog : http://forum.ragezone.com/f457/flyff-v15-official-setup-guide-repack-658914/
If you look at the end of the post, you can see the list of Ragezone's members who thanks this guide ("Thanked by : ..."). 2bartz is one of them (at the start of the list).
More ?
Okay. Here, the link of the post where 2bartz introduce his server, Giolog : http://forum.ragezone.com/f115/flyff-giolog-flyff-server-v15-659623/
So, now you are convinced that our 2bartz and this 2bartz are the same person, I believe
And, as you saw on the 1st picture,
the last activity of 2bartz on Ragezone is dated of : 1 Day ago.( And, his last post on Ragezone, dated of three weeks ago )
How much time does it spend to let a short message to his server's community ? Maybe a little bit more than 10 times the necessary time to log in Ragezone...
