Hi r_scurtu
I am a "newbie" like yourself and have purchased 70 domains for about $500 US. For the month, I have made $1.26. I guess I consider the $500 spent thus far as my "education investment".
I have learned much off the boards here -- my next $500 will be better spent.
Can you list some of the purchased names you have? I have purchased many four character .com names where the .net, .org or .cn has been registered.
My next group of names will be purchased through Moniker only after testing.
Bill
