The 4 major sanctioning bodies you'll need to know are the following : WBA, WBC, IBF, WBO. They all grant world titles in 17 (soon to be 18) weight classes. People at The Ring magazine publish their own unified world rankings and grant titles. That's a lot of belts. To know if a world titlist is for real, you'll need to check out his record and see which fighters (and at what point in their career) he did beat to earn and keep his belt .
www.boxrec.com comes in handy. Undisputed champions - those who got all the silverware in a weight class - are for real, but they're uncommon.
Use the search function wisely. There are tons of threads in here about people's favorite bouts.
Learn about the "10 points must" system and the actual scoring criteria (clean and hard punching, effective aggression, defense, ring generalship). If you're not familiar with them your opinion on the way a boxing round - let alone a boxing fight - should be scored is very likely to be irrelevant.
A different scorecard than the judges's is perfectly fine provided you do know about the rules. Never, ever call a close fight a "robbery" even if you disagree with the official decision. Judging is a subjective matter and you're not the one who gets to decide. Knowing your shit isn't about being "right" all the time. It's about understanding to what extent people can see the same fight differently and still be correct according to the very same criteria that you've used.
If your English isn't too good, spend the time you'll need to make your posts readable. People will be kinder to you.
Avoid Jake Paul-related discussions.
Also, Clinton Woods.
