Hi, I am Rhyme and I will be assisting you today.
1. If people are not noticing your topics, head into the chatbox. Try your luck there. You may also post a topic in the Chat board asking for someone to RP with you. (I will also offer my services but I'm having a little tie-up with my characters. I'll notify you through PM if I can offer a slot.)
2. You can start off anywhere in the RP world. If you have a character that's new to camp, I will point out that most newbie characters start at Half Blood Hill and Thalia's Pine.
3. Any good pictures? Unfortunately I'm not one for face claims. I will note that you should probably glance at the Face Claim thread in the Chat board to make sure you don't accidentally become someone's twin.
Hope I was of some assistance! ^^
