i have a question
1-if user A set URL path to (for example : sina) --> site.com/sina/profile
2- in backend , disable user : sina (no deleted just disabled)
3- if in frontend another user try to set URL : sina (for example user B , set url to ; sina) , can ?
i testing , user B can not set url : sina, because user A URL = sina
if user A = sina and disbaled user A , and another users try to set url to : sina , can not? It is true? no bug?

No that user cant, because the sina alraedy on database, except you totally delete the user

thank you this is good
my solution :
if community site loading with basic domain : site.com
please follow step by step (for example for URL administrator)
1- create user A and set URL to administrator ----> result : site.com/administrator/profile
2- in backend disabled user A
3- after , another users , when created , and set url to administrator can not, because user A , set url to administrator
user A not display in front end and access with another users :)
this solution , can used for another link (site.com/forum , site.com/article , site.com/images or media or any site.com/MENU_ITEM)

this solution good? In your opinion Good and logical?

that is accepted solution lol, but the nice solution is like I said on prev post :)

Thank you
i using my solution because i want to load website community with main domain : site.com
i do not want load community with : site.com/communirty
if create hidden menu (with your solution) , Sure , site community loading with site.com/community ?
can not create hidden menu and used your solution but jomsocial loading on main domain ? : site.com (without slash / and community)

for fastest solution you can follow your idea, its really smart to be honest :)

I set this topic resolved now :)

Thank you very much
