Here's a listing of other Warhammer webzines to get ideas for our own one:
Druchii Herald
Da Warpath Quarterly
Citizen Levy (look on bottom left side)
Skavenblight Gazette

Let me know if I'm missing any, and I'll update the list.

Skaven Webmagazine.

Now I'm a bit embarrassed....I took the links to the other magazines from the Skavenblight Gazette forum. :P

The Watchman from Warseer.

Letters of the Damned, a great Mordheim fanzine.

Total Power was great in its day as well.
