As I create topic I can add: 1. Name 2. first Message in topic. So it would be great to have an option also to pin first memo with RULES or DESCRIPTION/PURPOSE of new topic.
Are you suggesting the first person to create a topic controls that topic? Or would the first message be immutably pinned?
Could there be a topic owner command (or whatever the appropriate term is) for whomever created it and then admin commands set by the owner? Genuinely don't know, just spitballing.
Memo = permissionless. However, 1st message should have option to be highlighted. I see 2 ways: 1. - pin 1st message 2.- highlight 1st message with color frame + instant scroll button.
It can't be done as an opcode, cos memos are immutable. For filtering u have to tweak the UI side and u can add such things as moderation - selective show of memos
no, not control the topic. I just propose to add option to pin first message. Creator can pin it if its important in case of rules or to describe purpose, or not to pin.
