Hi, Mr. Manlobeiro.
You have just claimed BJJ training. Now they (we) might ask you Lineage. One of the joys here. JJ has so many false ranks posters do not get excited, but BJJ will get them (us) all hot and sweaty.
Nunes jumping grades and fraudulent ranks in JJ will not interest most. I will look this up again in about a month (no time now). If you could provide a link or contact to someone who claimed that Nunes said he was BJJ rank, that might get things going.
