Like all the best PSA's, many who need to read this info and learn from it will not :-(
I stay pretty busy and keep everything up to date so I'm easy to research if I can't reply in a timely manner, but I figured out a long time ago that guys may not always have your info in front of them when contacting you. Some guys are PM'ing from the mobile version of eccie, or they have saved your email address to send you a message when they have a moment alone, and they don't actually have your ad or site up when composing the email.
I'll answer most reasonable questions sent to me unless it's about rates and services. If it's obvious someone is pulling my chain with a million questions I'll ignore them, other than that I try to accommodate.
