From a newbie in need:<BR><BR>I have 3 tables:<BR><BR>1. User Profile Table (Contains *UserID* and general user details)<BR>2. Message Table (Contains message details and *ToUserID* and *FromUserID* fields)<BR>3. Blocked Users Table (Contains *UserID* and *BlockedUserID* fields)<BR><BR>The UserID in table 1 matches the ToUserID in table 2 to give the list of messages for that user. That's working fine. However, I want to add one more step. I want table 3 to contain user preference data about which FromUserIDs they will accept messages from.<BR><BR>My question is how is this done?<BR><BR>I know there is a simple answer... but my simple mind isn't finding it.<BR><BR>Thanks in advance for any help.
