Pro members can give a link to an External Journal for their campaign, displaying their characters and handouts for anyone to see, even outside Roll20. (There are minor problems with the feature: Journal entries don't Zoom like for registered players, and the entries are in alphabetical order by title, with the folder-structure of the Journal lost.) My main suggestion is that members should be able to place a link to the External Journals for one or more campaigns (of their choice) in their member Profile as well. This may be useful during the Looking for Group phase so a potential player can click for a Profile and see examples of how the GM sets up games. A new section of the Profile could be set up called something like Campaigns the Member Has Displayed.
