Hi Petar, and welcome!
Since jowori's user name shows up in black, it means he is no longer a member. He might rejoin at some point, so keep on checking.
In the meantime, may I invite you to tell us a bit more about yourself in the "Introduce yourself" section here
? In an effort to help thwart spammers, Mr. Delcamp now requires an introduction from newly registered members:
The accounts of new users who have not introduced themselves within a few hours of registering are deleted, and they will need to register again.
You will get a proper welcome and some tips on how to get the most out of the Forum.
