Congratulations on passing the rigorous screening process to enter The Writers' Block. Ignore the blood curdling shrieks from the upper levels. They do primal scream exercises to free the creative spirit. At least, that's what they told me; i haven't had the nerve to peek just yet. (For all i know, it's really just MadLews arguing with himself.)
There is no set number of assignments for this level. You may get kicked upstairs after one or two, or you may hang around for four or five assignments.
General Goals for Level I
1. Find your creative voice. Get in touch with your 'inner storyteller.' Or whatever other metaphor you want to use.
2. Get used to the review/edit process, and not take it personally.
3. Get a sense, from the responses to your work, of the sorts of things you focus on in the editing/revising process.
Miscellaneous Housekeeping and other Fiddly Bits
No time limit or word requirement on posted assignments.
Post assignments as a reply to the thread where they are given.
Life being what it is, it may take as long as a week for me to get to reading/reviewing your assignment.
Don't get upset about the nit-picking. No one finds all their own mistakes. i have editors and proofreaders for my own work for that reason.
Enjoy the process. Be open to outcome. Writing is a journey; not a destination.
