Welcome to Pokecommunity! I see that Sapphire has already contacted you, so I'll just say a few things.
First off, be sure to read the rules before doing anything else in the Roleplay Corner, just to avoid making mistakes and, if you're new to roleplaying, there are guides to becoming a better roleplayer at the bottom.
Second, if you want to ask questions about or want to join a specific roleplay, go to the Roleplay Lounge and talk in the OOC threads for the roleplays. If you need general help, or just want to talk about roleplaying in general, head to the Roleplay Discussion Thread in the Roleplay Corner.
Also, I don't know if you know this, but if you want to reply to a VM (Visitor's Message), go to "View Conversation", or the person you want to talk to's profile and type the reply there.
So welcome to the community, and if need more help, don't hesitate to ask :)
