I have just edited this WordPress codex page for WordPress version 3.4.
The Network Admin Link has moved with each major release of WordPress, as this is still a work in progress. Depending on which version of WordPress you are using, the link can be found in the following locations:
- 3.0 – A menu called Super Admin
- 3.1 – On the admin header by “Howdy, YOURNAME.”
- 3.2 – On the admin header, as a drop-down under “Howdy, YOURNAME.”
- 3.3 – On the admin bar, as a drop-down under your “My Sites”
- 3.4 – A sub-menu called Network Setup under the Tools menu
