As Sales said, you have to set
serverr variables on serverside. If they could be set clientside, a "hacker" would be able to change the news for everybody.
The reason it works until you reconnect is that you're temporarily changing the
serverr variable on your client only. When you reconnect, the server sends the actual variable. It's like setting a
clientr variable on clientside. The value will stick (at least for a while?), but you won't have actually changed the variable on serverside.
Also, RC will trim any server flags down to a certain size (~255 characters?), so if you set server flags with RC, you'll permanently lose anything past that many characters.
You should probably
use text files instead of
serverr variables for storing server news. There are very few times when
server or
serverr variables are advisable.
