How easy would it be to remove the races?
if you could give me some intructions how it'd be helpful.
I'm pretty new to this smaug stuff, in circle I know my way
in and out. so please help.
With the races if you want to "jump in and hope" approach, remove the field in CHAR_DATA that defines the race (its an integer I believe in stock smaug). Then make clean and make again.
If your code compiled cleanly before, now you will get an error for every use of the race field, and thus know where the code needs to be changed. This is no small job, I know as I switch from integters to RACE_DATA pointers when I converted my own system from a stock Envy.
The alternative is search for every reference to the CHAR_DATA race field and modify the code, but the "jump in and hope" approach reveals the location of these fields better in most cases.
If you are new to the Smaug stuff you might find it time consuming, but races are a integral part of the gaming system as such. What you may find easier is simply to have one race and have everyone and everything as that race instead, and prevent there being options to choose an alternative race.
While its wasteful on space as you are still storing the race information, for which everyone has the same info it is probably the simpler approach.
