Clans are the most popular.
To get a big group on roblox, you must be popular or, invite people and you can invite your friends too.
Make some friends.
ask
You have to make the uniforms then sell it so your group members can buy them.
To get a popular place on Roblox you should ask your friends to go, make fake accounts and make them go to your real Roblox's place, or save up money, make a GOOD ad (I suggest using and mastering Paint.NET to make your ads), and put it up.
You need to be a leader of a group and click 'Group Admin'.
There is no popular group. Make your own, be nice and make a ton of friends.
You can get a popular group on Roblox in several ways. One way is to create a group with a lot of interest then invite a lot of people to join it. Otherwise you can Just invite your friends and tell them to invite friends and so on. Also, if your group is inactive it will not likely grow, so do stuff with it.
Minecraft is definitely less popular than roblox
You don't make it, ROBLOX makes it itself, then you can build on it.
Either make clothes that look really good and get a lot of sells, make a place that gets really popular and is fun, ect.
