I saw this information in a group, I thought cool, and would like to share with you!
Linden Lab has now officially announced that they have indeed enabled 42 group max on the server. In their blog post they also discuss some other exciting changes current and in the near future.
In expectation of this 40 group limit, Phoenix Viewers 725 and 818 already have support for them,
-however you have to enable it in the debug menu first.
-Here is how…
1. If you do not already have the advanced menu open, click on the Phoenix Menu, next to help at the top and click “Show Advanced”
2. Click the advanced menu, look down to the 4th from bottom and click Debug Settings…
3. Type in phoenix40GroupsSupport
4. Set the drop down below that too TRUE.
Thanks for the info Sylwia Obolensky
