Okay, here's a guide on how to get dynamic clan-tags that will change as you play. (if you walk, fire, stab, jump etc)
Note that this isn't useful at all, and is just for adding some l33t stuff next to your name on the scoreboard. I'm making the guide as some people asked how it's done.

There's two ways to do this, either by creating your own groups with your own clan-tags (it can be anything) or join the groups I've made for myself which will cover:

• Moving.. WASD (note that it will set your clan-tag to W if your'e going forward, S if backwards etc)
  
• I'm firing
  
• I'm jumping
  
• Inspecting..
  
• Opening.. ("useful" for E? (+use))
  
• Stabbed ya (BM when you stab someone <3)
  
• Swapping gun
  
• Talking.. ("useful" for voice)

Links & Clan ID's
So, if you would like to use my groups, here are the links & clanID's. (you'll need the clanID)

• Moving.. W - http://gtm.steamproxy.vip/groups/zzzzzzzzzzzzzz123123 - (ID 9911600)
  
• Moving.. S - http://gtm.steamproxy.vip/groups/fsfdfsdfsdsffxzc13/ - (ID 9911605)
  
• Moving.. A - http://gtm.steamproxy.vip/groups/asdxzc131dd1/ - (ID 9911613)
  
• Moving.. D - http://gtm.steamproxy.vip/groups/dsfsdfxzc311323123/ - (ID 9911614)
  
• I'm firing - http://gtm.steamproxy.vip/groups/sad21e12d12d21d12d/ - (ID 9911617)
  
• I'm jumping - http://gtm.steamproxy.vip/groups/asfasfzxc12e12/ - (ID 9911619)
  
• Stabbed ya - http://gtm.steamproxy.vip/groups/safzxcvczxczxc123/ - (ID 9916452)
  
• Swapping gun - http://gtm.steamproxy.vip/groups/asdzxcewf3wr243r34f433f/ - (ID 9916815)
  
• Talking.. - http://gtm.steamproxy.vip/groups/dsfsdfsdasdzxcw/ - (ID 9916830)
  
• Inspecting.. - http://gtm.steamproxy.vip/groups/asdzxcwf3f121331ff3/ - (ID 9916999)
  
• Opening.. - http://gtm.steamproxy.vip/groups/asfxz1er4g444 - (ID 9917010)
  
• Reloading..! - http://gtm.steamproxy.vip/groups/dsfsdsffdsfsdxccxvvcx (ID 9917021)
  
• Crouching.. - http://gtm.steamproxy.vip/groups/ffad3113313131 (ID 9917017)
  
• Walking.. - http://gtm.steamproxy.vip/groups/dsfsdsffdssfssfsdxccxvvcx (ID 9917026)

After you have joined the groups, or created your group(s), you'll do this to bind it:

I'm firing - bind mouse1 "+attack;cl_clanid 9911617"
Stabbed ya - bind mouse2 "+attack2;cl_clanid 9916452"
Talking.. - bind z "+voicerecord;cl_clanid 9916830"
Moving.. D - bind d "+moveright;cl_clanid 9911614"
I'm jumping - bind space "+jump;cl_clanid 9911619"
.. more examples/full config with the binds for my groups shall be added soon, if wanted. :-D

Commands:

• cl_clanid - Change/view your clanID to be shown.
  
• +attack - Normal attack
  
• +attack2 - Attack 2 (stab, silencer etc)
  
• +voicerecord - Voice chat
  
• +forward - Move forward
  
• +back - Move backwards
  
• +moveleft - Move left
  
• +moveright - Move right

More commands can be found at; http://www.gamerconfig.eu/commands/counter-strike-global-offensive/

Keys:

• mouse1 - Mouse button 1
  
• mouse2 - Mouse button 2 (etc)
  
• Keys are just "ABCDEFGH", except numpad and other special buttons.

If you made your own group and you're looking for the clan-id, you can either equip it through the game settings, and type cl_clanid in the chat, and it should print something like "cl_clanid = '13993149'".

Or you could visit your admin page, by clicking "Edit group profile", and then you should see your clan ID like this:

You should also note that the "Abbreviation" (might vary depending on your Steam language) is what you'll see next to your name.

Create a .cfg file and put it into your csgo/cfg folder, and use "exec configname" in your console.

Note that this is just for "fun" and useless.
If I'm not being clear on something or that you need help, feel free to comment.

You can use this (cl_clanid) to just bind different clantags or other message if you would like, I've just given examples how you could use them.

If there's any interest I'll add more examples and fill it out a little more.
