I checked this article out the other day, & it has some really good free apps/programs for your computer.

One that I found to be really helpful that it listed, we ourselves could use in our own industry is actually just a shared organizer type site for offices etc. With some companies having remote workers it acts as a virtual office where you can see when someone is off on vacation on the calender, when business meetings are and the notes for it etc. Has a little message board to have you all in communication and no for sure of new tasks & goals assigned & even sends email & txt message reminders for deadlines. It seems as if I'm jerking off this thing but I just think it's a really good asset to anyone with remote workers. Heres the link to it,
