Free Form Role Play, or commonly abbreviated as FFRP, is as its name suggests - a system that can be based on any, none, or all existing systems. There is no fixed list of skills, no character sheet, basic or no rules on combat, casting and character creation. By-the-book gamers look on in horrified fascination at such a lawless realm, but then again, roleplaying by-the-book involved a lot of ROLL-playing and very little ROLE-playing. FFRP is the art of spinning tales with independent characters played by different people in an environment pre-defined by the founder.
A lot of roleplaying is based on something most people tend to leave behind when they switch on the computer and log into the Internet - courtesy and common sense. Remember to take those with you the next time you roleplay, and the rest should be easy.
A thing I often see is people taking things that happen IC personally – as an attack to the player and not to the character. Most of the time, this assumption is not true. Strife well-executed between two characters can contribute to good roleplay, story and character development. If someone suddenly decides to hate your character, it does not necessarily mean he hates you. It happens sometimes, and that kind of behavior is just a display of immaturity.
Similarly, OOC should not be taken into IC. Say for example two people who are friends IC and OOC. One day, these two friends have a fight. When they meet IC, their characters start fighting for no IC reason. Hmmm…
* Having a modern name like Cyberdude in a medieval-fantasy chatroom.
* Using out of period phrases like "What's up man?"
* Overusing swear words. Some channels allow moderate use of swears but most are kept PG. It's always safer to stay PG in language use.
