Womens Techmakers is a great site dedicated to Women in Technology. It is a Google-run site and organization that can provide a lot of stuff. Not a lot of recruiters try to source there. The reason is simple they do not know how. Well to do this without worry you need go no further than into your bag of tricks and pull out an old tried and true tool, a simple search with some extras, and a whole lot of website searching
So to source within Womens Techmakers you have several choices. First, you can go on the site to the directory and simply search by location. You can also go to the communities area and search and find groups, and people such as LatinaGeeks, or you simply need to use a skill known as xraying, like the one below.
If you run the strings above in google you will get the results below.
You will notice meetup groups, communities all with info within them to help you find the people.
