A quick search of the IW FAQ found these:

Can I send email to other members? Yes! To send an email to another member, you can either locate the member you want to contact on the member list, or click the Email button on any post made by that member. This will usually open a page that contains a form where you can enter your message. When you have finished typing your message, press the [send email] button and your message will be sent instantly. Note that for privacy reasons, the email address of the recipient is not revealed to you during this process. Note that if you can not find an email button or link for a member, it either means that the administrator has disabled email functions for this forum, or that the member in question has specified that they do not wish to receive email from other members of the forum. Another useful email function is the ability to send a friend a link to a thread you think they may find interesting. Whenever you view a thread, you will find a link somewhere on the page which will allow you to send a brief message to anyone you like. Your referrerid is added to the link you send, so if your friend registers on this forum as a result of viewing the link you sent to them, your referrals total will automatically be credited! Registered members may also be able to send messages to other members of this forum using the private messaging system. For more information about private messaging, click here.

What are referrals? The administrator may have enabled referrals, which allows you to be credited for any new users you invite to the forum. You gain referrals by promoting Ironworks Forum using your unique referral link. The link you should use as your referral link is this: http://www.ironworksforum.com/forum/...eferrerid=8823 Each time someone follows this link to Ironworks Forum and registers as a new member, your referral count will be incremented by one. The number of referrals you have can be viewed in your profile. Your administrator will have more information on any prizes or rewards that may be given out for referrals. Please be courteous when promoting Ironworks Forum by not spamming other web sites with your referral link just to gain referrals.

Did you do either one of these?
