Information of FeatureBan WeaponBan and Fragban. If you are trying to decode that fragban number you see in the gamespy extended info, readon. (You can see the number in the extended info of Gamespy--if you dont understand forget you saw this page-- it is not that important)
 

If you run a server, you probably know that the Quake II engine can accept certain variables when setting up the server to turn certain options on or off. The WOD mod expands on this idea letting the server ban any weapon or prevent the user from scoring a frag from using that weapon. There are certain numbers associated with items such as the blaster or the homing rockets. These numbers are based on a binary progression, where each number is double the value of the previous number. (i.e. 1,2,4,8,16,32,64,128....) When you add these numbers together you get a sum that is unique because you can only use each number exactly once. When the number is displayed in binary form, the(00101001) ones correspond to each specific value. This is a little tough to explain and doesnt really matter. The result is that if the third digit from the right is a one, then you will know that "4" has been included in the sum when the features were added together. (All you see is the sum like 135331840, which need to be converted to binary which would look something like this 0010001000001 and you could compare this to a chart and figure out which 3 items were included.)
 

It is too much trouble to convert the decimal number into binary and try to match up the 1's by hand. If you have the list of decimal numbers with the corresponding features in front of you, just look for the largest number on the list that can be subtracted from the total feature/fragban number. That item is definitely included. Subtract that number out, and repeat with the remaining number. If you do it right, you will end up with a zero and a list of numbers corresponding to the features that are banned. The list of features and weapons is included in the server readme file.
 

To do this automatically, there are probably utility programs used by computer programmers. I don't have any of these, but I wrote a spreadsheet that does it for the fragban list in WOD. I didn't bother with the feature/weapon ban list because if the weapon is not there then it just doesnt matter. And the number for weapon banning is the same as fragbanning, so you can use the same program.  The real problem is when the weapon is there but it doesnt count. Its nice to know before you waste time using it. So I have the file in Excel old 2.1 version, later  7.0 version a macro version 7.0, and (data interchange format). You can try to use it in your own spreadsheet program. You will need to have excel or Lotus or maybe Works, (something that can read one of these formats) to make this work.

Some of the clans like ASK have gotten together to try to define a set of feature/frag banns to havebetter competition matches. I have a copy of te Competition WOD FAQ from the ASK clan here updated as of April 99.
 

I don't know if there is a simpler trick to decoding these binary key things, but the spreadsheet  seems to work.I pulled the info below from about 20 servers, it will give you an idea of what features are usually being banned. these servers have probably changed their fragbann features since I posted this.
Most servers like to ban the homing rockets, cataclysm device, and telefrag. If you are wondering what to ban, I strongly suggest the cataclysm, as people will abuse it and ruin the game for everyone. They can constantly respawn and pick up the grenade launcher and immediately fire a cat killing themselves and anyone close by. I've seen people do it for 15 minutes straight.
