Hey there! There is quite a lot that goes into making a new group. I might have a few tips for you!
1. Make sure that you are active. It is very important for the leader of a group to remain active. Doing so will result in more of your members staying active!
2. If needed, make sure that you decide on a recruiter account sooner rather than later. If you have staff members/multiple leaders it can be important to have a recruiter account. It makes it very hard to add the recruiter later as you will have to disband the group and reinvite everyone - and that can be quite difficult.
3. Make a Discord for the group. This is a great way for everyone to keep in touch and it is also a great way to build up your community. If you'd like some ideas for a Discord server, just shoot over a PM and I can help you with that!
4. Have a plan. If you have a group that you know that you would like a plot in, make sure that you have that planned out so you can answer any questions that may arise.
5. Don't give up! Starting a group can be very difficult, and at some times it may seem like it is a lost cause or pointless, but whatever you do, do not give up! More people will join and the group will thrive as long as you keep on trying with it!
6. Advertise! Whether it be on the forums (I have a group advertised in my signature on the forums) or in The Grounds, you want to make sure that you advertise it so people know what your group is about!
7, Have fun with it! It is important for you to have fun also! Whether that means some funny roleplays, movie nights, or anything, you want to make sure that you do not get stressed out and give yourself the well-deserved breaks!
I think that is all I have for now! I can answer any questions that you may have since I have run many groups in the years that I have been on the game. I do hope that your group thrives and that you have fun with it! I hope that this helps!
