Overall, I heavily prefer walls and rooms for roleplaying. PM is for plotting/ooc inquiries or content that is not suitable for public spaces i.e. or rated roleplaying in general.

‣ writing style

I almost exclusively write in 3rd POV. That's not to say that I can't do 1st for smaller replies, but for the larger, more official ones, I prefer 3rd. Furthermore, I enjoy replies that are at least a paragraph long. As with length comes time. Longer replies will take a longer amount of time.

‣ plotting

I prefer plotting over random starters. Winging is okay if the muse is there, but most of the time, plotting is superior in my book. Don't approach me if you don't have an idea in mind. I often don't care who writes the starter. It's usually a toss up to who is willing and/or has the time at that moment. 

‣ reply speed

I tend to be slower when it comes to replies. That's only because I value quality over quantity, so keep that in mind. However, my reply speed can also be directly tied with my muse level. If I really enjoy a plot or person, I will likely have a faster reply speed, but don't count on that. It's not always indicative. Communication is key here. Let me know if your muse drops or if you'd like to not continue roleplaying.
