There are plenty of women online making money. I'll give you to a link of a forum owned and run by a Minority Woman and she has some pretty good stuff in there. (It took awhile for me find it in my 65,000 unorganized bookmarks. LOL)

Now, after I've put these links up for you, I'll tell you right here and now, WickedFire is going to be THE BEST resource for you out any online marketing forums, if you can get past all the smart assing going on here. It's OK though, you TOO will go a little stir crazy after awhile of working in this industry and THIS is a great place to come and unwind a little and grab some info as well if want it.
Back to WHY there aren't as many woman online as men. For one thing society gives women Dolls and pampers them. Boys are given Guns and taught to tear things apart then try to rebuild them. Men are risk takers and most women look for safety/security.
Jsut a short little differential in the above paragraph whitout getting into a lot of detail. So, since the two sexes are treated differently men are more inclined to take the RISK of building something online. That and as my woman says, "Geek Speak makes my eyes GLAZE over." She is a Writer and is online about 18 hours a day. But, she could care LESS about programming languages or knowing the difference between FAKE RAID and TRUE Hardware RAID.
Now there are MANY women who have broken from the constraints that society has tried to put on them and they've done WONDERFUL things that have improved the quality of life for EVERYONE.
So, don't be discouraged about the lopsided ratio of Men to Women in this industry.
Stay the course do "your" thing to the best of your ability and DAMN the rest!!
