Revoking License

Hello,   I want to uninstall the plugin to install on a test site so I can get to know the workings of Newsomatic before going live on my main site.   Am I right in thinking that I can revoke the license and then reinstall on the test site and activaye license again?   Then, once familiar, do the same to have it back on my main site? <h1><span class="gs-sub-heading"><b>Newsomatic</b></span></h1>
