Fedora :: Cannot Save Files In Codeblocks IDE Nor Can Get Eric IDE To Function Either?

I can not get many things to work as I have no way to access root priveledges in Fedora 10. I tried before to install fedora 11, then 12 and hit roadblocks. The problem was both went through long installation times and then simply said not enough space in boot file. I then tried to remove images as it said and could not boot at all as I received an error saying something like file missing and it returned me to the boot screen. I then reloaded fedora 10, went through the over 700 ! security upgrades and set it all up. My problem is several things I try to set up I need root priveledges to setup. I can not save files in codeblocks IDE nor can I get Eric IDE to function either, also the same with a neat looking game sauerbraten.

I am happy with Fedora 10, everything works on the hardware side, my cdma sprint net connection works flawlessly, even my wirless works most times. I can not get to root at all, when I try to use the sudo ed it asks me for a password for ed then returns ed is not in sudoers file this incident will be reported. I tried sudo root and it asks me for root password and I give it correctly three times and then it says 3 incorrect attempts and exits. I can not get into sudoers file to edit as I have no permissions. I set up another user and group with id 101 (lowest I could use) and included all the groups in root - halt, shutdown, root etc and when I switched users and tried to access root as Edward no permissions again. I then tried sudo Edward and it asked for my password again, I used the proper one and still got the message Edward is not in sudoers file this incident will be reported. Also it seems to me I should be able to get into root through the switch users, I tried typing in root then the correct root password and that just returns to the prompt again. I know the root password is correct as I use it access the Aunthentication app and the users and groups app and it allows me access to these as root?.
