Custom home page for sub-server user

Hi every body,

just a quick question of what i don't know what i have to do, so thank's for any help:

how can i custom the sub-serveur user home page, i explain:

now in the home page of the sub-server user, it show the quota for all the server, so me i want display only the quota for the current user, and for example the number of mailbox created...

in general i wanna display only the information about the user's sub-server.

Thank's for any answer.
