Please have a look at the plugin "blog", made by Ester http://wiki.splitbrain.org/plugin:blog
"Lists a number of recently created / modified pages from a given namespace in reverse chronological order. Every entry is linked to the main entry page and below the entry author, modification date and number of comments are displayed"
The list with all changes is not reachable with the button "Recent changes", but you could have a page with them displayed on it.
I think this is not exacly the solution, you was looking for, but I think it sould work for you? I would suggest the admin to close this task. Feel free to ask him to open it again, if you are not satisfied at all :-)
