I'd like to commend the developers at JoomlaTools for responding so quickly to my reporting of a problem with DOCman 2.0. They got onto the job straight away and fixed the issue. There's heaps of extensions out there, but not very often do you get such great support (even from paid ones!).
The other thing is that DOCman is a great extension and I'm excited to see all the additional features of DOCman 2.0. It's worth all the work to upgrade.
