Great link, however I would strong advice to use "THE BETTER/HARDER WAY" and
not the "THE LAZY WAY".
Further I would recommend that you use either and offline computer to generate the vanity addy or make sure that you computer is free from malware.
Vanitykeygen work great with 7 digit keys (1XXXXXX), it takes around 1-14 days to find the key with a normal office PC.
