Script style

This style is also known as "bracket RP" or "casual RP", among other names.  As the name "casual RP" implies, this type of roleplay is accessible to everyone. The reason for this is that it's easy to grasp and easy to start. However, script-style role plays will rarely offer much character development or plot advancement; it's usually used as a "pick-up-and-go" roleplay for fooling around. The posts in a script-style roleplay will usually start with the name of the character which will be involved in the post, followed by dialog and action done by that character, and possibly, in-between the name of the character and the dialog, an emotion, most often in parentheses, with which the dialog will be spoken and the actions done.

To assist me in my quest to improve the general level of roleplays, I have created an assistant. Her name is Kara Chter. Let's meet her right now in a script-style post to concretely demonstrate what exactly script-style is:

Kara: (shy) Hi... *fiddles with the edge of her shirt*

This style of roleplay, as mentioned before, is casual; it doesn't require any amount of skill to play, except maybe the ability to make your posts legible enough for everyone else to understand. Because of that, this guide will not focus on "how to roleplay script-style". It will rather focus on the second type of roleplay.

Paragraph style

This style, also known as "formal RP", "mid-long post RP", etc., is much more intricate than script-style, and has much more potential for setting an atmosphere and describing actions and thoughts than its casual counterpart. This is what most people will say was meant to be true roleplay; writing a story collectively with one or more other people, each person using one or more character to make the story advance. People who roleplay with this style need a certain amount of concentration and attention to detail when writing. Roleplayers using this style want to make their posts look as though they were excerpts of a novel.

The posts in a paragraph-style roleplay need to be detailed enough to set a certain mood, although exceptions exist. This style most of the time requires a linear scenario, some sort of concrete plot. Sometimes, people will develop it as they go, needing only a setting to begin writing, and other times, people will decide part, if not all of the plot before even beginning on the first post. The latter can take up several hours – if not days or weeks – of planning before actually beginning, and will often feature longer early posts and a better starting morale from the players, since they already know what will happen; it leaves less room for uncertainty and moments when neither player will know what to do and would just make their characters speak with each other without much action going on. Planning lets the roleplay deliver action at a rhythm which every player is able to handle. Let's have Kara Chapter introduce herself again, this time in paragraph-style:

A woman stands in the center of the plain, unfurnished room. Her appearance is veiled by an indescribable fog, letting only her outlines and actions be visible; she appears to be of average size, and her arms, resting on either side of her body, allow her hands to tug nervously at the bottom of her shirt. "Hi..." she says in a timid voice.

It's undeniable that a lot more content is present in this version of the same post; it may require more effort, but it's worth it; the amount of detail dished out by this style if done correctly often prevents people from getting confused. That will prevent posts in which the last actions of the other character would be completely ignored, or posts that overlook certain crucial details. For example, I've tried making this last post as clear as possible (although still somewhat short) by describing the surroundings, what the others can see about my character, and her actions, so that my partner wouldn't wonder "where is this happening? what can my character see about this other character? what is the character doing exactly?" and wouldn't assume wrong. Though it may be difficult at first, experience should teach most people how to underline details in order to make the other player(s) notice it and have their character(s) respond accordingly.
