Now I have challenge is to restrict the number of admins for that group based on the role. Eg: I have created Groups "Developers","Support Tech" and "Testers" for Role A . Groups "Team lead" and "Sr. Developers" for Role B. Groups "Managers" and "HR's" for Role C. My challenge and need is Role A can allow 1 admin for Groups "Developers","Support Tech" and "Testers", . Role B can have 5 admins for groups "Team lead" and "Sr. Developers".while the Role C have can 10 admins for Groups "Managers" and "HR's". Is there any module to achieve this? Please help me guys.
