Personally, I'll do either one. I have noticed that there is a gravitation for PM roleplay's from the preferences of others. I wish people would RP more in the forums, though. If for no other reason, so that I could read their work when I am approached by them for a potential partnership in RP. But as others have already mentioned, PMs feel more private. And some people like their privacy. Though, I really don't know what everyone is so shy about. We have this big, snuggly blanket of internet anonymity. I am open to some subjects that are on a lot of members' "blacklist". But I would have no problem whatsoever writing about any of them in a place where any member could click in and read about it. I mean, as long as you aren't breaking any rules, it can actually be a great benefit in finding other writers with similar interests as you. This, especially if you have niche interests.
Also, I should mention now that peeps are outsourcing to Discord and other such host sites for the RPs. If you really want privacy and freedom from peeps looking in at what you're doing, I guess that's the best route. Personally, Discord is kinda cool if you have a big worldbuild project because you can organize it with all the channels. But the character limit is hella annoying. I love using google Docs for all my lore and character sheets. But I have yet to attempt any kind of roleplaying on Docs. I just use it as a linked resource.
But anyways, I digress. I actually LIKE for outside parties to read my work. I have even written some short works on-site for that very reason. And while I'm sure that the majority of members of BMR do not often go perusing the Forums to read random RPs being written by others, I still like the idea of the potential of some stranger being able to read my work and possibly appreciate it.
But when all is said and done, the BIGGEST reason I'd prefer the forums to a PM is simply because you can always go back and edit your posts in a forum. You can add in a pic, change a sentence or even a whole paragraph to reiterate a plot point or description, retcon something so that the story has a smooth continuum, etc. But in a PM, there is a time limit to doing any of that. And if you don't correct or change something in your RP in time, it's stuck there for good unless you delete the whole entry.
4) they don't want others to see who they are posting to/for...meaning, they don't want to deal with someone getting angry at them if they post to one person over another and/or
Yeah.... I tend to forget that people can be dramatic shit-starters. I guess this is a pretty good reason fi you are trying to avoid being dragged into a problem that wasn't even yours to begin with.
Partners can be fickle; one minute they're down, and the next they're in the wind. And I'd rather not litter the forum with threads that die within the first couple responses, so I keep all of my projects to PM's.
Can't you just delete the thread? At least the ones you make the opening post for?
