[galaxy-user] Help on installing cutadapt

Hi Galaxy users, I tried to install cutadapt for sequence trimming on a local Galaxy instance. I successfully installed Galaxy as an administrator. However, when Galaxy starts, I don't see the administrator option in the top menu bar with the "Analyze Data, Workflow, Shared Data, Visualization, Help, and User". It looks like the only way I can install cutadapt is with an administrator option. Any suggestion how I can include the administrator option in the menu? Thanks for your help. Tilahun
