Suggest Improvement) Guild banner invitation function

Hello, Arena net !!

**Many novice users do not enter the guild, which makes it difficult to learn and adapt to the game.

Also, the guild has no way to promote.**

I suggest a guild introduction, promotion, and invitation through the guild banner.

1. After installing the guild banner, you should be able to choose whether to activate the guild invitation function.

2. Be able to write a guild introduction.

3. I want to reduce the cost of making guild banners so that even poor guilds can promote guilds.

Thank you Arena net

Oh this is just what those obnoxious banners need on top of blocking view and NPCs: ad spam!
