No problem Michael. When I saw this thread I did another search on my own poems and have more to contact myself. I had a little time this morning, and thought I'd do a few quick spot checks for you.
This one has taken your poem "Need", renamed it and changed the very odd word. He's calling it his own Michael …
And another …
If you want to do a pretty comprehensive review, what I've found works best, is to have your author's page from the main site up in one window http://netpoets.com/poems/authors/0004000.htm , and go into one of the poems you want to search. Have the google search open at the "advanced" search section in a second window http://www.google.com/advanced_search . Choose a rather uncommon line from your poem, and copy and paste into the "exact phrase" portion of google, then search (I don't know if it makes a difference, but I always take the capital off the first word of the line I copied and leave off the punctuation at the end, as some people re-type it themselves and drop those).
I have a template letter in Word that I use and basically fill in the blanks, and e-mail it off to the offender as I go. I've found people to be pretty good about removing it entirely or properly acknowledging in some cases after I've contacted them. If they've taken full credit as the writer as they did above, I use a pretty strong letter and tell them they have 48 hours to remove it.
I know how frustrating this is … but hope this helps ...
