Well. I've been to all three, and I've been all three before... Here we go.Mate Center
I work the Mate Center by calling up the males most of the time, and if we're low on boys, then I go on a girl spree before choosing one of the males again.
BUT...
There is a way to mess up. Maybe two. Or more.
First Way
Having people whispering you.
If you're not organized, you're going to end up forgetting who's who and who's next. Then you're going to have an angry mob of Mate Beggars yelling how bad you are.
Second Way
Changing it up.
If you try to change it up, and start saying "Oh, females go to the males you like." Then "Okay, males pick which girl you want." One, it's confusing to people. And two, the males are just going to leave because you're forcing them to pick.
So that's my part of Mate Center.
Adoption Center
I think that the AC goes well with a MC around. If you spot people getting their short-termed mate, then see if you can advertise a link with Mate Center. That's what I like to do, though. Sometimes I tell stories to the pups. I think that the AC is not as annoying as MC, but there can be more pups than there are parents.
There are a few ways you can mess up, though.
First Way
Moving around.
The pups will get tired of moving around, and some of the AFK pups will never follow. So now you have a huge line of pups down the wall.
Second Way
Scaring the pups.
If you start telling Creepypasta stories, the RP-Active pups will start crying, screaming, etc. Parents will think the AC is a torture spot, if they are also RP-Active.
Third Way.
Not caring.
You have to be sympathetic. If the pups tell you about their "Tragic" past, you should feel bad... But in real life you can laugh all you want. Tell them that it's okay, and hope that he won't kill his new parents like he did with his others.
So, that's how I think AC should go.
Fight Center
I put rules and guides in my Bio, so I remind people to read it. Fight Center is hard to control, due to it being an uncommon center. I remind the two fighters the important rules. I have two strikes. If you powerplay, that's a first strike. If you do it again, then I'll call off the fight.
Due to it being uncommon, there are lots of ways to mess up, but it might just be your way to do it, since there's no right or wrong to controlling FC.
First Way
Attention.
If you don't pay attention to the spar, it might just go down-hill, and drag on and on. If it starts to do that, whisper the two fighters to start wrapping it up.
Second Way
Rules and Guides
Since it is an uncommon center, you have to make up the rules. If you make good rules, and continue to hop on and gain attention, those rules will start to become the Center's rules. But, if you make bad rules, you're just making a sight for trolls and power-players.
Third Way
Space
You need to make the space like a proper Mate Center. A full circle with lots of space in the middle. If you cram everyone into a tiny spot, it'll cause lag and it's hard to see who's fighting.
Fourth Way
Chat
You might need to make a party or a group for Fight Center due to the fighters. You know how Bonfire is. Busy and chatty. So, you should make a party/group. If you don't, the fighters might be confused and the watchers won't know what is going on.
And that's what I think about Fight Center, and how it should go.
That's pretty much it.
TL;DR
MC: Do it right or get hated.
AC: Be kind and sympathetic or the pups will run off.
FC: Make good rules or you will have a horrible time.-Sandfury
