One of my pet peeves are roleplayers who think it's my job to tutor them in how to write better. There are hundreds of RPs on the site, if I don't like your writing, I don't have to let you in my thread, and I don't owe it to you to instruct you on how to "write better".
Though honestly, the biggest thing I look for is punctuation and capitalization. I've met people who don't realize that quotes and dialogue have to be in quotation marks - it's not fucking decoration, it's English syntax. And if someone "doesn't care" about making sure that the first word in every sentence is capitalized, you think I'm going to trust that they care about other small details in my RP? Like, really?
RPing isn't a job, it's not school, I'm not grading people, I swear... but I'm going to choose people who have good technical writing and boring ideas over people with "bad writing" and good ideas.
Unless I'm in a real hurry, I type up all of my RP in Word and let grammar check warn me of any basic grammar errors. I strongly suggestion that anyone having issues with Capitalization and Punctuation copy their work into Word before posting.
