Sadly the last 5 or 10 pages of W@RF have been very messy. A lot of us have found the posts confusing and yes, someone has unfortuanately been creative enough to use the names of 'Lost' characters instead of creating something original.
Players post their characters in the RPG they want to join, because W@RF is so big we also made the character thread to post characters to W@RF in. Players can make more than one character, though the person who made the RPG can put a limit on the characters a player can create.
It should usually be clear (at least to people in the RPG) who is talking to who, if a person can kee track of their characters' situations. But W@RF has turned into a bit of a mess recently, so I imagine it's pretty tough to understand. I'm struggling a fair amount at the moment
Try reading the first few pages of W@RF 5. I think its clearer.
Oh, and as for the movement of action, sometimes if two or three members are on things can develop quickly but generally it takes a few days to get things going. People can't always get on more than one or two times a week but can still be successful RPGers.
