My office has folding tables as desk. As ghetto as it sounds, it's not *that* bad. I hang my shorts on the rear corner of the table. My PC (the tower part) is under the desk so I drape my jersey over it. I've never been told of the smell, but I start out clean, and I wash my gear at least twice a week.
I've only got 1 pair of shorts and one jersey. I REALLY need some more gear, especially with winter coming up. :/
The Glade plug-ins idea is a good idea. I may have to use that if my new office-mate (each office in my building has 2 workstations in rather close-quarters) decides to pipe-up and say something about my clothes.
