is usually fixed. A server updates the game after the turn-time has elapsed evaluating all the player's moves sent to the server. The turn-time duration can be hours, days, weeks or even months. Play-by-wiki A play-by-wiki game is played using wiki software instead of a forum. Because players' previous posts are editable and the gamemaster takes responsibility as the overall editor of the story, plot holes can be avoided and writing skills may not be as important for each writer. Wiki space provides not only a means of communication, but also a permanent archive and a designated off-topic discussion area for each page. Players can edit posts freely because records are automatically maintained and changes can be easily undone. Sites such as Wetpaint are commonly used for this. Role-playing blog The role-playing blog (RPB) is a game which is played out online using posts within a blog or weblog. Unlike message board role-playing, a role-playing blog is generally restricted to one gaming group, and the blog contains static files such as maps, archives, and character sheets specific for that group. RPBs often incorporate mixed elements of message board role-playing, play-by-chat, as well as play-by-email styles, allowing players to mix and match the style of play that they prefer. Popular blog sites used to host these games are Tumblr and LiveJournal. The style of role-playing on Tumblr often comes in the format of a 'main blog', the headquarters of the game, and multiple character blogs from which each player posts. The main blog often advertises for players through the tags of Tumblr. The main blog is where applicants to the game apply by filling out an application on the main blog, and where other such administration of the game occurs. The Roleplay game creator is often referred to as the "Admin" short for "Administrator" and players may be required to run major plots and game changes by the Admin before proceeding, making the Admin function in a way that a traditional GM might have. Players role-play by reblogging each other's posts and adding paragraphs of interaction from their own character to the end, each of which are called 'paras.' Often seen are text posts with dialogue and an accompanying .gif image expressing the character mood or intended expression of emotion. Though, recently .jpg icons have risen in popularity in some games. The style of role-playing on Livejournal style RPB's is maintained
