Hit up Bragginwrites, they got some good leagues going. Ran by some good heads.
www.bragginwrites . com
www.rapmusic.com has the RBL which probably has all the best heads on net that still text in there. Me and Oneduh modding it since other dude stopped. Word to me not posting on that site since 2004, but getting my name modded LOL word.
then on my site,
www.itzarap.com the $1,000 text tourney in final four. and me and Tettris starting up a new league. Gonna be money involved for every champ match you win. So if you keep winning champ matches, keep making dough.
Then uhh that's basically it. I forget that site Kempo had that listed all the open text leagues.
