what is tremded? 

I put the qvm in a folder called vm in the root folder of tremulous.
There is no error but I can't use trembot. 

How can I use the Trembot commands?I just don't understand what admin panel is. 

Is it something like the in-game console?
Do I need to click something in the mods button?
Also,how can I create a server without using the in-game create a server option? 

I use the trembot downloaded from this forum!!!
Additional information:I play Tremulous with friends through LAN.
Hope this answers/information can help to solve the questions.
I am totally a n00b and please guide me! 

I am very unhappy  

 because I just can't kill insects 

 with my friends.
