This is a huge work in progress of preferences being new to text roleplay in general. My experience has always been in the LARP community before this and I've been wanting to try to branch myself out into the text-based scene. So as I learn more of how I roleplay and what I enjoy these will change as I do.
On the topic of grammar and spelling as long as it is sensible it's fine for me. I know I still have a long way to go myself in phrasing paragraphs in more English correct grammar and I've been told by friends they can really see my second language show through without me meaning to so if you don't mind sometimes I might make my own mistakes and may need to be told 'that's not how that is phrased in English' I think we'll be in equal fields.
I really enjoy playing stories, plots, going through the ups and downs and the drama. I don't mind canon-type roleplay as well.
When it comes to actually doing roleplay or not you'll catch me when you catch me. Though if we do get started on something I'll be probably at least a check around daily for it, but otherwise it might take time between responses for talking or starting things out.
In general I'm mostly just putting some bits on here as a base guideline to get me started but who knows once I get going. If there's stuff I haven't marked or even if I have marked as no and you want to try you can always ask. There are some things that are hard no and others I just don't know if I'd be good at writing it, not that I don't want to write it at all.
