They do offer a Gold membership option, which gives more features and access to other members.
You can expect to have all the basics too, like sending mail, contacting which ever member you want, message boards, photo uploading, etc.
In the case of match doctor , you will notice that they do not focus very much on being an attractive site.
The layout is done rather poorly, with lots of scattered information.
With your account, you can contact members for free, keep a list of your friends and favorites and keeps a log of who views your profile!
Access to these features remains free to all members.
