Thanks for your feedback and taking time pointing out all typos. :oops:
We intentionally make it case sensitive and mix the upper and lower case, try to make sure that user will actually read EULA and agree to it. We'll think about whether this is necessary. For other input in the installer, they are all case insensitive.
It's very easy to change the port from web admin, click the name of the listener on the left, it will show the listener port and other info. click "edit" to change the port. then go to service manager (click "apply change"), click "reload".
"Watchdog" function is in place since V1.0. It can be turned on/off from configuration: Server->General->Server Process - Auto Restart. By default it is enabled. If you specify the administrator's Email, an email will be sent out in case of crash. If a core file is created and "gdb" debugger is installed, calling stack back trace will be included in the email as well. The event is always logged in server log.
I'll update all misspellings ASAP.
