Trading Etiquette says not to request a show until 2 weeks after it.
I trade with nancies.org and etree.org and have never had issues with either. I personally find antsmarching hostile.
I've got some great shows and I WILL send you some, I'll get caught up soon!
Post a thread on nancies or antsmarching NEWBIE ISO 8/3/02 B&P and you should get some replies. Etree you can email people who have the show directly--I think this is the most efficient way.
