[u]Pacing[/u]. Back in the days of yore, there was said to be roleplays that only moved at a pace of perhaps 6 posts a week, and had up to 14 players upon it. [i]Think about that.[/i]

To make such a roleplay work, a lot of legwork went into a post. [i]Offline-legwork.[/i] Sometimes this involved printing-out the last page of the RP, chucking it into a binder, and perusing it like a book as you write a cliff's-note on how you plan to summarize all that in your next post because there's a chance yours will be at the head of that page.

Also, sort things out before they start, an OOC arguement over a post you made will waste time you don't have. If someone ninja's your post, be prepared to edit.

2.
[u]Don't be afraid to dual-wield characters/subplots.[/u] Having two characters off their own ways doubles your chances of being able to post [i]something[/i] in an RP, and may be just enough to get you to roll right through writer's block.

3.
[u]Quality is better than quantity.[/u] This applies to players as it does to posts. Have ones that'll stick with you for the RP, get to know the quircks of each others' characters and have an established "continuity of RP" so that if someone AFKs suddenly, that someone can pick-up the notes you left behind and keep your characters relevant (or use your character if the group could've [i]REALLY USED YOUR HELP[/i]) so that nobody is ever stuck on account of some suddenly plot-pivotol character not moving for IRL reasons.

So get yourself a good band of friends that 'get' your thought process, try and include them in everything if you can. It's okay if they don't share ALL your interests, that's just the world's way of encouraging you to get more.

4. [u]Make sure you get the ideas in your head written down, even the silly ones.[/u] Especially the silly ones. Mistakes happen, and memorable-mistakes are meme-worthy.
