I have many quirks that some find annoying.I am a sucker for little details, having things true to the book/movie/manga/anime/play etc. I also hate when people have spelling mistakes, unless they are ones such as using the wrong word (using the word 'like' when 'as' should be used) or just the wrong meaning of the word (there, their, they're always come to mind).
My very few rules are:
1) PLEASE, PLEASE, PLEASE use spell-check before hand & read over your own work after spell-check, many common mistakes can be caught that way.
2) Do not, I repeat DO NOT use instant messaging, texting, short hand, or anything that is not the proper way to spell something (example: OMG or WTF/WTH? instead of 'oh my god' or 'what the f.uck/what the hell?'). The only exceptions to this are if the person actually says "OMG! What just happened?" instead of saying "Oh my god! What just happened?" and they actually say the letters instead of what they mean.
3) I will not check over poems, because I do not know if you have intended to have a lower case 'i' instead of an upper case one 'I'. I also would not know if spelling, grammar, or punctuation mistakes -or lack there of- is intentional or not.
See? I have little rules, and am happy to take on any project!
