Personal conversations, or PCs, are a way for users to interact with each other without posting in a thread. It’s sort of like a private thread between you and whomever else you choose to involve. To view or check any personal conversations you have, you can click Inbox on the top navigation. From here you can write, send, or read messages.
If you receive a personal conversation that is offensive or otherwise breaking the rules you should add a staff member to the conversation; they will review it and deal with it accordingly. Please do not take the situation into your own hands unless you feel confident you can work things out peacefully.
