clean up 

   * Thin client servers need two network cards when using the default network architecture:
    * eth0 is connected to the main network (10.0.0.0/8),
    * eth1 is used for serving LTSP clients (192.168.0.0/24 as default or 192.168.1.0/24).
-  * Consider 2 GB RAM for 30 clients and 4 GB RAM for 50-60 clients.
-  * Disk space requirements depend on profiles used, but any disk larger than 30 GiB will be sufficient for a workstation or standalone installation, 40 Gib for a thin-client server and at least 60 GiB on the main + thin client server. As usual with disk space on a main server is "the bigger the better". 
+  * Disk space requirements depend on profiles used when installing. 
+  * The main + thin client sever must have at lest 2 GB RAM for 30 clients and 4 GB RAM for 50-60 clients. 
+  * It's recommended 60 GiB on the main + thin client server. As usual with disk space on a main server, "the bigger the better".

+  * A disk larger than 30 are sufficient for a workstations or standalone installations. 
+  * A thin client server might due with 40 Gib. As usual with disk space on a main server is "the bigger the better". 
-  * Thin clients can run on as low as 64 MiB RAM and 133 MHz 32 bit processor, though 256 MiB RAM and somewhat faster processors are recommended.
+  * Each thin clients can run on as low as 64 MiB RAM and 133 MHz 32 bit processor, though 256 MiB RAM or more, and somewhat faster processors are recommended.
    * For running Iceweasel/Firefox and !LibreOffice, 512 MiB RAM is a minimum requirement. 
-  * For workstations, diskless workstations and standalone PCs, 800 MHz, 512 MiB RAM are minimum requirements. But 1024 MiB RAM will perform considerably better and are recommended. Just a faster CPU will speed things up. 
+  * For workstations, diskless workstations and standalone PCs, 800 MHz, 512 MiB RAM are minimum requirements. A setup with 1024 MiB RAM runs considerably better and are the recommended minimum. A faster CPU will speed things up. 
    * Swapping over the network is automatically enabled; the swap size is 512 MiB, and if you need more you can tune this by editing /etc/ltsp/nbdswapd.conf on tjener to set the SIZE variable. Please ''tune up the swap size'' either locally on the PC or on the server. Please remember that placing work station swap on the main server requires added diskspace to the minimum required space.
     * If your diskless workstations have hard drives, it is recommended to use them for swap as it is a lot faster than network swapping. 
    * On workstations with little RAM the spell checker can cause !LibreOffice to hang if the swap space is too small. Then the system administrator has to disable the spell checker on !LibreOffice or students have to kill !LibreOffice, resulting in loss of work. Enabling at least 1024 MiB swap on a 512 MiB RAM workstation solves this, and the spell checker runs smoothly. Anyways, we recommend 1024 MiB RAM due to extensive RAM usage browsing the web.
