I like the upgrade though I have had some persnickety problems. I also print a 15-20 page monthly newsletter for 4-H which we convert to PDF for our website. It is usually to large to email, but I used to isolate key pages such as calendars and sign up sheets (entry forms, etc) and send these to people in email or send to our IT guy to post on our website individually. With 2000 I could hit select all copy, and just open a new publisher document and plunk it in...likewise since many of my email list does not have publisher, I could select all, copy and plunk a page into word and send it that way. Now it is not that simple. I also have had no luck at all saving P2003 into older versions for those that have 2000 to read.
I was very attached to Publisher 2000 and hated to leave it. Pub 2003 definitely has some advantages...but somethings have been made more complicated.
