VMD test releases are made available in the VMD (Public) project on BioCoRE. Just create yourself an account (guest or regular) and you'll be able to download the latest test version of VMD from the BioFS shared filesystem found therein.

Once you have logged into your account, you can click on the Public Projects link in the left column to see a list of public projects and join the VMD (Public) project. Choose the checkbox next to "VMD (Public)" and choose "Join selected project(s)" at the bottom of the page. Then, change your project to the VMD (Public) project by selecting it in the dropbox in the upper right corner that shows the Current Project.

To access the VMD test versions, you need to navigate to the proper folder in the BioFS shared filesystem. The proper location is the "alpha" folder within the 'VMD (Public)' project folder. You can set your computer up to use WebDAV by following the (WebDAV access) link in the left column of the webpage, or you can use the web interface to navigate to the right folder by choosing the 'BioFS Shared Filesystem' link in the left column.

If you have any trouble, there are usually several of us logged into BioCoRE's Control Panel on chat that can answer questions. Support for test versions is provided through online chat on BioCoRE and via email to vmd@ks.uiuc.edu.
