While it's nice to be able to provide new suggestions and ideas about the new ARM Community website, I'm pretty sure that most users are completely oblivious about the existence of such section.
The main reason being that the "Ideas" link is only visible from the top navigation menu of the "Community Help" community, and I'm not sure that many people pay attention to this menu.
Putting it in the main navigation menu, after Communities, like this :
- About the ARM Community website
would increase the visibility of this section.
Splitting the link into a "menu"/"sub-menu" might be useful if you intend to add "Ideas" sections to other popular communities.
