[xwiki-users] Configuring the webhome page of main space?

Hi All, I want to configure the default home page i.e webhome page of main space. I am looking for these kind of customizations:- 1) Replacing *Welcome to your wiki *with Welome to *ApplicationName Wiki.*Though i can see the ways to customize the panel bars,browser title bar text but not the text. 2) Right now, on web home page under main space i can see see all the details(like what activity admin or any other users did . For example modification in existing page or creation of new page) on page just after login (i.e webhome page on main space). i want to hide these unnecessary details from specific group users? Is it possible to customize. i am not even able to find the vm file for this page so that i can do some tweaking in code?
