Chuck, I'm happy to help.
Go to the Writing Challenge home page, here:http://www.faithwriters.com/writing-challenge-intro.php
(You might want to save that link in your bookmarks of your computer for future reference.)
Once you're there, look at the links in the left column. Under "Entries," you'll see a link that says "submit your entry." Click that.
You'll be taken to a form to fill out online. The first box is for choosing a level--you should probably pick Level 1 for now.
Then you type your title.
Then you check the appropriate circle for fiction or non-fiction, and whether you want critiques.
Keep scrolling down. You'll see a large-ish box that says "copy and paste your entry here." Do that (you don't have to include the title again).
Once you've copied and pasted, keep scrolling down. You'll see three buttons: Preview, Submit Entry, and Reset. You shouldn't need Reset. I highly recommend clicking "Preview." It'll take you to a page that shows you exactly how your entry will look once it's submitted. If you're unhappy with the spacing, you can fix it--just "X" out of the Preview, go back to the previous step, and add spaces or otherwise tidy up your entry.
When you've got it the way you like it, click "Submit." You should get a message that says "Thank you! Your entry was submitted!" If you don't get that message, you may have missed a step. Try again.
If you have problems with any of these steps, or if my instructions are unclear, please let me know, and I'll try to further clarify. Happily, you have a whole week in which to enter.
