setting PATH environment variable

[omidkamangar]

Hi,
I want to add a new directory to the PATH environment variable on my FC6.
I usually do it by editing the .bash_profile file in the /home/omid (my user) directory and adding this:

PATH=$PATH:/new_folder_path
export PATH

where new_folder_path is the path of the folder to add.
Is there anyway to add this folder to the PATH environment variable permanently?
