lokeen I installed the main tag plugin
You also have to install the Pagelist plugin.
lokeen how to make the tag page
A tag page is created by default in the namespace :tag
. E.g. by creating a link to it and clicking on it:
[[:tag:this-is-my-first-tag]]
BTW: To use the Tag plugin it is not necessary to create a tag page.
