Yes, i found the *-1234 after the name in the url. Problem is I have thousands groups, when a user want to create a new group, not all of them will search in the group list to see if there is already a same-named group. In this way, there are a lot of twin group and i have to delete it (which will make user feel not good).
Is there any code to appear ‘this group name has already be used’ when the user create a same group? Thx!
