Which sites do you all find most useful,helpful, productive in terms of self promotion and marketing and auditions/casting etc?
Thanks

On both coasts, Actorsaccess.com. When emailing agents or cds, I think it's the best link to give because the clips, resume, and headshots are all in one spot.

ActorsAccess.com is #1.

For additional commercial and student film opportunities, CastingNetworks.com (NYC version of LA Casting)

To obtain theatre audition information Playbill.com, Backstage.com and ActorsEquity.org

I also like nycastings.com You can put up to 20 pictures, a media or voiceover link, for one low price. They also update their mail lists for printing labels for agencies/agents on their site, under Resources section. They handle union, nonunion, promo, voiceover, commercial, model, etc. Lots of helpful articles and interviews with people who working in the business. A couple times a year they put a $80-89 dollar yearly membership deal up, if you don't want to pay monthly installments. I notice that Casting Networks, is also good, but not as pleasing to look as nycastings.com, which tend to overlap along with ActorsAccess for some gigs. Afford what you can. For now I'm with Casting Networks and NYCastings.
