The first is the server's ability to work in a multi-tethered configuration (Enterprise license only). This basically means you can run more than one CRM organization on the same server. Very cool for hosted servers or very large deployments where business units do not "cut it".
The second is, to some degree, even cooler. It's CRM's ability to provice a multi-lingual experience to end users. Once a new language pack is installed on the server (this is on a per-organization basis which corresponds with the multi-tethered part), each end user can configure the language he'll be using the system in. This is great!
So far, Microsoft have released language packs in the following languages:
- Hebrew (not really released, but I've already tested a very final pre-release version)
All these language packs are available at the following location:
Make sure you select the language you wish to download from the drop-down menu and press Change.
After downloading, it's a simple matter of executing the installer on the CRM server and then activating the new language pack for each of the organizations on each server. This can be done through the Settings section.
