Maxum software downloads are complete, fully-functional packages that include time-limited software, full user documentation, and all support files. These packages serve two purposes:

Free Trial Software
We believe that you should not only be able to test software products before purchasing, but actually be able to use them in a production system. This means that Maxum demonstration packages are complete and have no limitations; they simply stop working at the end of the trial period. If you decide to purchase Maxum software, you will receive a serial number and validation code that will permanently enable your trial software.
Version Upgrades
Maxum product downloads are also used for both no cost and paid software upgrades. When you need to upgrade, simply download the updated package and validate using your serial number and validation code. When upgrading, be sure to review the "Upgrading" article included in the package for special notes about upgrading from a previous version.
Previous Release Archive
We always recommend running the latest version of Rumpus on a compatible server OS. However, for existing Rumpus users who need to maintain older servers, a previous release archive is maintained.
Rumplet is a small, lightweight desktop applet that makes drop shipping files through your Rumpus server quick and easy. It is not run on the Rumpus server, but rather on any client computer from which users need to be able to send large files to outside guests. The Rumplet application can placed on your desktop for ready access, or placed in any other handy location on the client.
