i've been debating the idea of getting my dad to join...my former roommate registered but hasn't gotten to submit yet, and i also told my boss about it.
but generally, no, i don't advertise, unless you count wanting to have a few of my friends on here with me as advertising.
Ummm, if I remember it was more about the clause that allows DPC rights to use the photographs or something they misconstrued as giving all rights to the photo over to DPC.
I plug DPC all the time. Every time I run into another photog, I ask if they've heard of the site and encourage them to take a look if they haven't. It's such a great place IMHO - I owe most of what I've learned to DPC & its members.
Every chance I get! Ive helped 4 people sign up (daughter,both sister-in-laws and childhood friend from back home) I have also gave the site addy to both my pain doctor and my phyiscal therapist who are both avidly into photography. I mention DPC in myspace and my yahoo 360 blog. If it wernt for DPC I would still be shooting snapshots!
I certainly mention it to people I think might enjoy it...
I don't link to it - where there are opportunities to link to a site I link to my new photographic prints site (link in my sig, below) and/ or to //www.mamtaskitchen.com (Mamta is my mum).
