I would like to know how new members enter the dorm system and were does the duels take place at?

do everyone just head to duel network or is there a special format that works for this place?

To get into a Dorm, for Slifed Red it's 30 YGO points, which is easy to get. All you do is duel people in the BA area for points. Also, there is other places on the forum that gives you points as well, which I will not be saying where, cause that'll be takin the fun out of discovering for yourself. I would post a link to the dorm and ranking area, but only phone so I can't. Instead I'll tell you where to find it. Up at the top where it says 'Home' 'Forums' 'Members' and then 'Ranks & Points' <--- Click that one up at the top. I hope I helped ya out!!!

Since I am on my laptop I will link ya. http://www.duelacademia.com/h5-ranks-points

Just to build up on Kurono's post, yes duels take place in DN or any other dueling platform if both duelists agree (for example both want to use ygopro, no problems for us, its your choice). Then you post your results in Battle Arena with screenshot just in case. Of course for BA match to be counted you have to agree with your opponent that you duel for BA, otherwise someone could just stack up all screenshots he played and just give it to us to collect points lol.

observation#3:YGO points are used to advance in ranking.

Thanks mrs.kurono and mrs.amy for the help.
