Hola!
Welcome aboard…
Look in the DCM Archives and Collections section, near the top of the front page of the site. There are a number of archives of heroic women hosted. there. Probably Shenna, of the jungle, has the most stories with a female lead on DCM. She's in the Fiction House section in Jumbo Comics, and her own title. In the Hillman Comics section you'll find the Black Angel in Air-Fighters Comics. I can't remember if she lasted until the book became Air-Boy Comics.
Have fun! But, please, remember to come up for air, now and then.
