If you are making a search thread, to look for a partner, it belongs in the Main Hall.
If you are making a roleplay thread, to actually roleplay in, it belongs in the Roleplay Hall.
The Lounge is just a general chat forum, like the GD.
The Break Room is for mods only.
Each forum is clearly labeled with the type of thread that goes in it:
1x1 H E A V E N
A meetup guild for 1x1 roleplayers.
