SDL Trados Business Manager Team: this is a standalone product for small teams that supports the sharing of a single database if it's saved in a location on a server where multiple users can gain access to it.

You can ask any question you like in the Business Manager forums. To make things simple it makes sense to create a new thread for different questions so they are easier to track and respond to. We created the forums to try and group the questions appropriate to the version of Business Manager you're working with and hopefully make it easier to find a solution for what you're looking for.
We also have a wiki where we publish full documentation for the product as well as dealing with the more common things we find people asking about.
