Here is the easy way to get somebody else's strips...
1) Log in.
2) At the top right, click "your comics".
3) When this new page loads (this is your "profile page" incidentally, editable via "edit account", also in the top right) go to the address bar in Internet Exploiter and delete your username, replacing it with the username of the person you are looking for.
4) Hit the Enter key, wait for the page to load, and you should be looking at your friend's profile page.
eg. Let's say I'm looking for the legendary comics of kaufman. I go to my profile page (http://www.stripcreator.com/view.php?author=DexX) and replace "DexX" with "kaufman". That's all there is to it. Oh, you can just delete the "&ref=Forums", if you like. Doesn't matter.
Another good idea is to put your friends into your favourites list (accessible via "edit account"). This streamlines your search for their comics (click "your comics" then click their name in your favourites) and also tells users who like your comics whose stuff you like, in case they are looking for more good stuff to read.
