We need to upgrade from our current Intralink 3.4 to either Intralink 8 (or 9) or PDMLink by mid-2008. Our VAR is pushing us to choose PDMLink, although I've been hearing many problems with PDMLink. We are a medium sized company and Intralink has been working fine for us thus far and I don't want to add complexity if we don't need the additional functionality. Suggestions?
