Men!
Yesenia,
Yes, what Mokoa said is great. Just post in the section that you're interested in advertising in, and start with the topic button. You can also add an attachment and if you're interested in that, let me know and I'll walk you through it.
Your showcase IS very nice and it works in a similar fashion to attaching a photo in the body of your ad.
And don't leave! Keep trying and you'll get it. I'm betting that there are plenty of men who would like to see you stay.
Sincerely,
Elisabeth
P.S. And please join us in the ladies powder room! Lot's of information to share and camaraderie. Shameless plug for that section of ECCIE but it really is a great place! And you're welcomed there.
