sorry, i may have asked the other question wrong. The current logo on the website (www.comonetwork.com) is not the logo they will be using. I'm making one for them , but I'm not quite sure what icon or symbol to use. I want something that wont confuse this site with another, and I want it so that it can be easily recognizable and catchy. Thanks! :) Its gonna be a "how-to" site, where you can go to find out how to do things, read tutorials, even post your own or edit others.
