Francesco Fullone wrote in with some new information those near Rimini, Italy should take a look at - this year's Italian phpDay 2008
This year's Italian phpDay 2008 that my pug (GrUSP.it) organizes in Rimini is coming at the end of May. This is the 5th edition of the event, and as usual it will be free for all. The main topic on this year will be the goPHP5 initiative, so there'll be a lot of talks on php5 only frameworks, migration, and other related topics.
Francesco and his fellow user group members will be hosting the even this coming May on the 23rd and 24th in Rimini, Italy. They've posted their Call for Papers to their wiki too. They're looking for papers around their PHP5 theme - migration between PHP4->PHP5, CMF and CMSes, Cross-platform/language programming, etc. You can also sign up to be a sponsor for the event too!
