I can't find a way of re naming a project in the PDMW vault.
Does anyone have the faintest idea whether this is possible and if so, how?
you need to use the Vault Admin tool to do this. There is a projects tab in the tool.
Vault Admin is the best choice but there is no direct "rename". You can create a new project, move the old files into it and then delete the old project.
