Start your own thread.
The way I run the game, we'll often have more than one thread active at the same time. Having the Mission briefing and gearing up thread active simulteneously speeds up the game, for example.
But I'm not the only one who can start a new thread; you can too, within reasonable limits.
Here's an example:
Donovan wants to check out the African Dream club. In the thread where PCs discuss their options, he post the following;
Guys, I'm going to check up the African Dream club.
Then Dononvan's player start a new thread and
links it to his latest post in the previous thread.
The title of the new thread includes SPYCRAFT as well as the title of the current season (Blood Money). He adds a subtitle that is descriptive for the scene.
SPYCRAFT Blood Money (The African Dream)
Half an hour later.
Donovan is driving through the crowded street of Harare, whistling along a coloful song playing on the radio. He is using the cheap car he rented earlier and just hopes that it won't let him down before he can get to the pretty chick in the famous club!
Note 3 important thing.
1-The first post commited Donovan to going to the African Dream club but didn't imply that he was immediately gone. That's how you should always do it.
Other PCs could comment on the decision and decide to join or declare different actions and propose a meeting point. I would expect Donovan player to keep participating in the previous thread and to answer his team mates question as long as is necessary.
2-The new thread doesn't step on my prerogative. Donovan's player doesn't describe the club itself, just Donovan's attitude as he is headed toward the club. The player could go farther and describe minor incidents as he goes. I'll have the options of picking them up or letting them go, but either way they'll add color to the game.
3-Donovan's player do not comment on whether he is alone or in a group.
ANY player could just post in that thread and pipes in to start a conversation with Donovan, establishing the fact that they were there all along. In fact, I expect it. A team split more than 2 way is just asking for trouble (as well as being harder for me to manage!)
Sooner or later, I'll join the thread and push the story along by describing the bar itself.
If you wish, you may e-mail me to notify the start of a new thread.
This is your game too and you should help me write the story within the limits set by your roles as main protagonists.
Is that clear for everyone?
