Should I delete the posts?

Shucks Warren...... Right back at you!.... Well I am going to leave it as I have done it... is it time for a beer yet? I have been at this project for hours. I think it is time to go onto another for a bit anyway!...

It really depends on the terms of each individual site. Some have no problem with duplicate content and others penalize for it. As far as Google, I couldn't care less. I get higher quality traffic just being myself and posting where I have friends (like you Cindy).

Thanks Joy.... Let me tell you what I have done.. while waiting for a reply.
I posted them on the new site... and I have deleted them off the old site.. BUT. I left the name and then I put something like... Bummer.. I have moved that post you can find it here with a link to the new post?
Now I am going to do a bit of editing on them in the site that I have moved them to..

delete and wait some time, then make a little bit change and post to new site. otherwise google recognize as a duplicate site
