Only after both of you accept the answers to these questions will you be able to send direct emails to each other. The goal of this directed process is to ensure that you are still interested in each other after you get a little more familiar, but it also helps ensure that you could have a comfortable first date.

When communicating on, the process is quite interesting and does help you learn about your potential partner and yourself. The waiting process also gives you time to explore other options and to make sure that you are not just over-eager, but truly interested in pursuing each match. provides at least 5 match suggestions daily so you will always have potential partners to review and contact.

Before sitting down to complete's member profile, make sure that you have at least 45 minutes to focus on the task. But don't be worried about the length of the registration process - the questions are extremely interesting and contain a mix of text-based multiple choice questions and questions that are based on various graphics and images.

Customer Support is one of the few dating sites that offers phone support as well as email support. A representative will answer your call between the hours of 9am and 8pm CST from Monday through Friday. I placed a call at 1:36pm EST on a Monday afternoon, and received an immediate response from a representative who was knowledgeable and courteous throughout the conversation. She was able to answer my questions quickly and efficiently.

I emailed them at 6:20am on a Sunday morning:
