Hello there...O Curious One.
Is it good? I believe that all is good and well with the idea of Online Roleplaying. It helps one to thinks better, hence improve imagination ability. It is also a good way to express one's inner feelings, in a few instances. Enhances self-esteem? Probably, dude. One of the ways that I cheer people up is by doing roleplaying. Since it benefits all in a good way, all is good. Thus, I safely conclude that RPing is alright.
Enlightened, O Curious One.
