Up until a few days ago, it was possible to search for postings strictly by poster's name. When I tried to do this the other night, it told me that I needed to put something in the key word field. Why did this get changed? It was a really useful feature!
I still search by posters name and have good luck with it as I am still collecting my postings. In my case I put fran in the keyword field and fmarrs in the poster field. All you need is a word that is in most postings. Some other words for that section are the, a, yarn, and knit.
