Hi, I have looked in to this and found no other posts on the subject. To be pro you need 10 silver and 1 of 2 things either
a guild name containing the words "SUP BRO" creatively interwoven in to a catchy phrase. OR you can make your guild something more along the lines of "BRB Bowflex, 8 minute abs etc. then "and shower". using one of these guild names is guaranteed to get you results! from fan clubs and trade channel rants about you, to 2k rated teams! This is one of our testimonials.

[note: this character no longer resides in the guild "SUP BRO WANT SOME POINTS" due to family complications, however that is the name he used to become so pro.]
