Any Newbie announcing a new coin or project should at least be a copper member. Being a copper member would allow them to display graphics and formatting. I would prefer the responsible person or people in the project to start the thread rather than asking any other people to do it on their behalf. Anyone starting an announcement of ICO with text only goes straight to cheap scam attempt category in my classification.
It seems to me that the question is not related to the design of the topic. The reason is different. Not everyone trusts people who don't have a reputation on this forum. Some people believe that the main indicator of a project is its presentation on the forum by one of the well-known users with a reputation.
