As stated basically everywhere, I don't RP like I used to, nerves got the better of me and now I feel as if my skills aren't worth it. However, I too tend to stray from RP's that require you to join a site. I'm already busy as it is and a site just makes it more inconvenient, and it's a Roleplay, I don't see the need for a site to be perfectly honest.
From past experience, site's can just cause more drama and useless fights that would have been avoided without having one altogether, I'm not saying all roleplays that do use sites are useless, as some groups are very well developed with information and a site is a very good way to keep it all together, but those kind of groups are rare nowadays and from what I've heard most RP's only last a week or two.
If I myself was to create a roleplay, I wouldn't use a site. No need.
