1) Have a create new topic button on the admin menu tab
2 ) is there a way to hide the Mysites – from other users except admin ( as I do make use of a multisite)
– if its not possible is there a way to customize it from My site to something like “Site Tool” and a way to change the W – logo to something else.
In all Thank you very much, as I do appreciate your help and assist
