Easy way to suggest tags

The Peoplesoft spaces were recently consolidated and it has become extremely difficult to identify content if you are, say, a Payroll for North America customer who doesn't care about Absence Management or Global Payroll (or any of a number of products that are all in ONE location).

In the previous version of the forum, you could create your own tags. Now it is no longer possible to do that.

We need an easy way to:

a) suggest new tags

b) have those tags quickly approved

so that we can categorize/filter our content.
