Though I've yet to create a thread of my own here, I prefer the proposals in 'Limitation' rule A, rather than that in B, purely because a month can be a very long time when you're suddenly hit with inspiration for a RP, and have to wait because you've already got one going. :3
I do like the idea of guides, and I agree with what Deoxys said- a group of people collaborating would be good, and I'm sure a variety of opinions/ experiences/ advice would be more useful to someone needing a guide than those of just one person. I'd also be happy to help with these- I've been doing this stuff for a long time, so there must be something I can pass on. XD
Personally, I've never had a problem with writing less than a paragraph whilst being here, but there are times where you can only have a character converse/ react to a limited extent, and you have to prattle on about various other things that don't pertain to the current situation. Filler can be tiresome to write, too.
