James U,
Sheri’s Ranch Courtesans can only respond to their in-house email when physically at the brothel. This is not their personal email accounts but a Sheri’s Ranch system. It may be that the Ladies to whom you sent messages have not returned yet. You might check those Ladies’ schedules to verify. In addition, you may “tweet” some of the Ladies if they list a Twitter account.
