My experience with iGear, and some tips and tricks:
iGear will block a substantial portion of E2, if you're using the URL everything2.com (without the www.). You can login, get the main page, and use the Search box at the top of the page. You can vote and use the chatterbox.
What you CAN'T do is click on hardlinks, you must go and type them into the search box. Softlinks work, but you need to erase the "index.pl" part of the URL, between the / and the ?. You can't create or cool a node without erasing the "index.pl" , and you can't click on a finding in the writeup, you must go back and type the whole thing in at the top.
If you type in the name of the superdoc, like Message Inbox or Node Heaven, you'll go to it, but none of the subpages without erasing the "index.pl" part. Sucks.
I discovered a few things. First, Safeweb is dead and gone, so you're forced into reading E2 straight. What you can do is erase the "index.pl" part of the URL, to get to the page. Also take off the "&lastnode_id=" part of the URL.
Going directly to a link, such as http://www.everything2.com/index.pl?node=Mr+Rogers don't work.
Instead, go to the main page, and type it in the Search box. Or use the node_id, like so: http://www.everything2.com/?node_id=624964
The program is still futile in some ways. If you use a program like the dialecticizer(www.rinkworks.com/dialect), or babelfish(bebelfish.altavista.com), you can grab the text from a page, as it's being redirected through a server.
You could use one of E2's alternate URLs, like http://www.everything2.com, http://everything2.com, http://www.everything2.org
My school blocked the first one, but the other ones worked fine.
One Warning: Copy your nodes before submitting them. iGear has this very unplesant bug where you spend an hour on a w/u, hit sumbit, and...you're thrown back to the login screen. AARGH!! Happened twice to me, lost whole pages.
