So, I've been experementing with TSO Pre-Alpha's messaging function. And experement, I did! I found out there are 6 types of messages. Type 0: Maxis logo, red inbox text if unread. Type 1: Maxis logo, yellow inbox text if unread. Type 2: TSO logo, blue inbox text if unread. Type 3: Letter icon, peach inbox text if unread. Type 4: Admin icon?, green inbox text if unread. Type 5: House icon, pink inbox text if unread. I'm not fully sure what each (I'm not sure about Icon 4 as well...) colour reperesent. If anyone knows, please let me know! Here's a screenshot with all tyes of messages in the game, not read. (Keep in mind that this is PRE-ALPHA!) I'm working on Pre-Alpha for NIOTSO + Project Dollhouse, in case anyone was wondering! EDIT: The one that is highlighted is Type 6 and above. the only difference is that the text is underneath the highlighted option bar.
