I have been trying for years to make money online and have failed. I found this forum and hoped that I could get some advice on how to make money off domaining as well as an appraisal on my domains.

clickflippin.com (As soon as the buzz started with "life after adsense" I got this one)
hands-free-cash.com
bigdreamlife.com(pr3)
how-to-on.com

all are undeveloped at this point.(if i had a mind for content would probably try to develop) Thru up a quick forum on clickflippin.com but not sure if that was the right route. I've blown over 20k in the last 8 years and have only made nickles and dimes. should i quit or keep on?

Sorry to hear your tough story. However, don't quit. The names listed above IMHO don't have much value especially those with dashes (-). Try to avoid names with dashes and more so reg domains for revenue based on OVT (overture) score. Check for ovt at www.ovtd.com! Good luck!
