Looky here. My good friend, Lawery James, is just so dag-gone nicey nice, that he wants to encourage
anybody that can poke their fingers at the key board to be able to send their stories in here. So if you can't spell, and you can't punctuate; If you think a sentence is something your Uncle Marvin got for stealing a car, and your grammar was unhappy about it. If you think a paragraph is one shy of a threeagraph -- heck bring it on.
But I'm gonna tell you what... the better you do those things, the better your story is gonna be.
There is just not much excuse for horrendous spelling anymore, except that the author is too lazy to run a spell check on the document. (The ability to electronically check my spelling was what prompted me to by my first computer -- 20 years ago!) With the exception of Windows Word Pad, even the most elemental word processing program has a spelling checker. Find it and use it. I think many email programs have a spell-check. If nothing else, here's the address of an internet spelling checker:
SpellCheck.netAnd for pity sake, do not use chat room or text messaging shortcuts for legitimate words, kwim?
If you use a word processor like Microsoft Word, it may have a grammar checker as well.
Punctuate as best you can, and use upper case letters where appropriate. The only reason for not using upper case letters is being too lazy to push down the shift key.
If you're going to publish your story here, separate the paragraphs with two carriage returns (push the "enter" key twice). Tabs won't work.
Here's the bottom line. There's no reason to post anything on here, except to have someone else read it. So you're really not writing it for yourself, you're writing it for someone else. And let's face is, there really are some established rules for constructing words and sentences, and the closer you come to playing by those rules the more readable and enjoyable your story will be.
You owe it to your readers to give it your best shot, whatever that may be.
