It's cool. For someone knew it' easy to get lost. I know I was and sometimes still do even after my years as a memeber here.
I love to RP so hopefully this many answer your question/s.
The friest thing you should do it read the rules to the RP part of the forum found here: http://www.phantoms-opera.com/showthread.php?t=3010
You then make up a character. What they look like, how old they are ect. Everything to fill this part/questions out:
Occupation: (Dancer, opera singer, stage hand, performer etc. to whatever your heart desires. If this is unacceptable then I will ask you to kindly edit!)
You would then post these answers in a NEW thread under this section of the forum in your characters name:
Now, if I remember correctly your first character doesn't have to be approved by a memember of staff, though it is good/nice to ask them.
Once that it done you then can start RP.
You can P.M memebers of the RP part of the forum to do thread with you or simply ask by leaving a message in either one or two places.
The genral place is here: http://www.phantoms-opera.com/showthread.php?t=4604
And the other place is found here: http://www.phantoms-opera.com/forumdisplay.php?f=147
In the 'unmasking' part of the RP forum. The unmasking part is also something you'll need to do for your character. Make a NEW thread with your characters name as the title and then write a little about your character. Mostly what makes them tick.
Remeber in the long run you are allowed to have 4 characters but remember they MUST be approved by the staff.
I hope this answers any questions you may have. If not please feel free to P.M me.
Hope to see you around.
