Hi, I use Ubuntu with fvwm2 as my window manager, so I don't use Gnome, and don't have an "Applications" menu.

I suggest a small edit to the wiki page Installing BOINC on Ubuntu: in the section "Starting BOINC", add the words "or by running "boincmgr" from a terminal" at the end of the second sentence: "You can then start the BOINC Manager from the pull-down menu ''Applications -> System Tools -> BOINC Manager''."
