Here is my thoughts. Can't say too much about #1 that hasn't been said.
2. Update of RPing guides and resources
This is the one I agree with the most. Some of the resources, while helpful, could be made better, as well as a couple of new guides to help out some newcomers. However, not a lot of people read the rules and guides, well, not to my knowledge, but it would still be worth it to write up some new guides for the people who do. I'll be happy to help, but there's not much I can say that hasn't been said, unfortunately.
3. Enforcement of the one-paragraph rule will be loosened
I'm a little iffy on this one. While it allows for shorter posts, it can also backfire, if people just write one-liners, and SPAM posts. I know, it's still against the rules, but it can still happen, and it might. I'm not saying it didn't already, but it could be a little bit more of a problem, in my opinion.
4. Suggestions for new sticky threads and possible rule changes are now open
Well, I suppose this is neccessary, and I really can't say much about this, unfortunately.
