So, I note that another writer on this site (T. S. Fesseln: Go read his stories!) is looking for a proofreader. As might be evident, I proof read, edit, and generally massage my own stories. I do the best that I can, but, in common with every other writer here, I have a life. This life involves a job, spouse, other family, hobbies (other than writing), sleeping, and suchlike. Therefore, I move my scribblings forward with painful slowness.
All of which is to own up to the truth of the re-stated adage, in my case, "A man who is his own proof reader, has typos, misspellings, and word salad as his product".
