Thank you for the question.  <3<br/><br/>If you take a look at the profile skeletons (now located in the first post of the character sheet thread), you'll see a smaller profile skeleton labeled as the 'tagging profile'.  This will be required to be posted at the top of all IC posts.  It details a bit of useful character information (which will likely change on occasion, depending onwhat your character does) as well as a 'Tagging:' space.  Here, you will list all the characters (or NPCs) you're reacting to.<br/><br/>For instance: Your character in Janis.  She has decided, within her post, to speak to Mark and and the NPC Lewis.  She also notices David but hasn't decided to directly interact with this person, yet.  Your 'Tagging:' space would look something like this: "Mark, Lewis; noticing David".<br/><br/>Essentially, this makes it easier for other players to skim through posts to see if their character has been mentioned and whether or not the post is directly relavent.  Sparrow and I have been in a lot of group RPs in the past where there have been huge posts and reading the entire thing just to see if our character has been mentioned gets very old very quickly when there are a good number of people posting.  This will lessen that annoyance by some degree.<br/><br/>As for grouping/invading other groups...<br/><br/>We recommend PMing the players of the group in question before making a post to 'invade' them.  Why?  They might be in the middle of a building plot, or headed to the bedroom.  They might also be posting faster than you do, so the sudden post of your character's actions might be belated in reference to the others too (or more).<br/><br/>Examples!  Janis wants to speak to Mark and Lewis, but she doesn't notify them before doing so.  She posts, and other actions are no longer relavent to the situation.  Things becoming confusing and backtracking may be required.  Or worse, your character may be left behind.  On the other hand, David has PMed both players, they have discussed the current (and potential) plot, and have decided that Dsvid should post after Mark.  They have established post order, and they're all on the same page.  No one is unintentionally left out and the story moves on smoothly.<br/><br/>Linking at the bottom of the page...<br/><br/>Again, this is not necessary, but when moving between threads with your character, a link to the first relavent post in the destination thread is helpful for referencing and for those who may be reading.  Links to particular posts may be obtained by copying the link in the title of your posts.  The title should, for example, read 'RE: [The 'Verse: A Firefly/Serenity RPG] -- Ariel'.<br/><br/>Example: Janis is on the ship Halethena.  She's landed on Ariel and will wishes to deboard.  In her last post on Halethena, she will have a link to her destination post on Ariel.<br/><br/>I recommend that I'd you wish to do this, you play around with it.  Feel free to do so in this thread.  :)  Copy the link of this post, open a new tab, and paste that link.  Ta da!  Now you, too, have the power of specific-post linking!
