You can create teams in your SlideCamp account to manage who sees which materials. For example, you can separate your marketing, finance and HR departments into teams which will allow you to share presentations with the correct people.
On the SlideCamp dashboard, select Teams from the drop down next to your name.
Add a new team by clicking + New Team.
Give your new team a collective name, and add in the email addresses which you want to invite.
View all your teams on the team page, and edit them when necessary.
