Instead of spending some money with the indicator of groups, you should put a block and just write what you want, using the Pages system, in your AdminCP.
1. Under Pages, go to Blocks and create a category. After creating the category, create a block and name it Groups Name Indicator, or whatever you like. 2. Go to Content and write the groups you want to show there, like AdministratorsJunior Moderators you may change the colours of the groups if you want.
AdministratorsJunior Moderators
Should show as I demonstrate.
3. You come back to your website/forum and open the editor (It might show on the left-side of the forums. 4. When opening Manage Blocks, you have to look for the Pages category. 5. Find category and move Custom Blocks to anywhere you want this to appear in. 6. Edit the block and select Group Name Indicator (or the name you used). 7. Save setting and there it is. You can edit this block on your AdminCP, by going to Pages Blocks.
You can customize, put some titles, other positions, some information and even take advantage of this block and do whatever comes to your imagination, it's really customizable.
