* If you're actively looking for a group or for players, make sure your option for "Send Notification Email When a Private Message is Received" is set to yes so that when another member contacts you, you'll be notified by email immediately. (This option is on by default when you register)
* In addition, you can also setup your options to allow other users to email you. Email addresses are only revealed to confirmed members. Spam Bots cannot see this email address.
To setup PM and Email notification options, go to your UserCP and click on Edit Options. Then look in the "Messaging and Notification" section. You'll see the options for allowing other users to email you and for receiving emails when you are PM'd.
