show only specific plan(s) on registration page

Hi
I want to show only one (or specific) plans of CBsubs at registration page (and NOT all like standard).
How can i do that? May somebody help me?

This i found....
If you want to show a registration page with only a specific plan you can send users to the plan URL (provided at top of every plan when editing them) and this will display only that plan pre-selected with registration.
....but what does it mean ..."send users to the plan URL" ... where/how???

regards

Plans show on registration completely based off the parameter "Allow registration:" and/or "Propose spontaneously plan at registration:" on the workflows tab of your plans. If yo want a registration page that shows only that plan then you can provide the user with the URL while editing a plan in the header; see "Url of plan to display only this plan ('-' to display multiple plans):". I recommend reviewing your CBSubs documentation as this and more is explained in greater detail.
