You can actually connect with other members at iCubis by sending them a message through the iCubis system.  This feature is found at the top of each profile page.  Click on the Messages button and then click on the Send Email option.  This brings up a window that allows you to compose an email that will be sent from iCubis, but with your email address in the From line, so if the member decides to reply, the return email will be sent direct to you.

You do not get to see the member's email address when you first initiate a message.  This helps protect our members from email spam harvesters.  Only if the recipient responds will you get their email address.
