I lost It!!!!

Oh my! After I posted my 1st opps, I got another small fish! While I was writing my 2nd opps, I kept refreshing my computer:) and????? when I was ready to submit my assignment, I accidentally click the wrong opps which I don't like to write about. I tried clicking the opps that I originally reserve but it said "All of the available posts for that opportunity have already been taken":( Damn! I lost my reservation for the opps that I already wrote. Now I might end up writing the opps that I've been ignoring for couple hours now.
