I'm not a picky guy. Send me a NarutoxSasuke fic, sure. Ichigo tentacle-raping Tatsuki? Alright. I really don't judge.
But be polite. Please and thank you are common courtesies, ones I quite enjoy. And text-chat, I just do not approve of.
If you send in something with no grammatical sense, whatsoever, horrible spelling, and broken mechanics, but ask me nicely to help you, then by the time I hand it back, it'll be a shining gem.
And time-wise? Don't expect me to take a full week. Chances are, you send it, I read it over. I fix the spelling and grammar. I double-check. I triple-check, and find the rest...You should get it back that day, perhaps one or two later, at most. I work fast, and efficiently.
Most interestingly, I do my research. In Naruto fics, I try to make the occasional Japanese joke, for example. I'm not perfect at it, and only really fluent in English. When writing for a series, I'll re-watch or read it, to get a feel for the atmosphere, and to notice those cute little things like Harry Potter's Fifth Year schedule. The entire thing.
My schedule is erratic, and computers have a habit of dying on me. So, I have every possible file backed-up repeatedly. Any lost data, won't be yours, but you may be unfortunate enough to end up waiting an extra day for me to sort out what to do with the smoking ruins of my latest disaster.
I'm a strong writer, a solid proof-reader, and I still recall what it's like to be new to writing. I won't mock you for not being at my level, but I'll tell you how to reach for it.
