This page is designed to clear up confusion between the automated code checker results "PASS" and "PASS-L". I've included links to other pages of the Users' Guide that help detail some of the explanations.
Very basically, PASS means you display the navigation on the registered URL, PASS-L means a link must be clicked to see any of the navigation bars. Naturally, there is a bit more to it than that, which follows.
Keep in mind that while your membership can test "PASS-L", this does not guarantee that the ring's manager will allow your site to remain active. Many managers don't recognize "PASS-L" as a valid test result and will require a full "PASS" in order to be active in the ring. Managers do have the ability to specify to automated management whether to accept PASS-L or treat it as FAIL. If your site tests PASS-L in a Ring requiring PASS, your membership will be suspended as if it FAILs.

In order to "PASS", a site must display the proper coding for that ring on the registered URL. The registered URL is the URL you have designated as the page to which visitors arrive from the ring during navigation. Proper coding in this instance is either working SSNB or individual HTML. If the WebRing being navigated appears on the registered URL, this generally is good enough for a PASS result (if you have this set up, but still do not PASS, use Why Sites FAIL as a troubleshooting guide).

In order to "PASS-L", a site must display the proper coding on a correctly-linked page off the registered URL. To be correctly-linked, the HYPERLINK must contain the word "WebRings". The words "rings" or "links" are not valid; graphic links are also not valid. The checker is looking for phrasing that is clear to visitors exactly where the rings can be found. The checker cannot validate a graphic link and alternate phrasing may confuse visitors. WebRings are not links (which are generally considered arbitrary favorite sites you list on your own with no agreement or guarantee of a link back) and should not be treated as such.
If you pull the no-script section (also called link-to table) of the SSNB to use because you cannot or will not use JavaScript on your site, this will result in a PASS-L test result, also. Anything that causes the Ring being navigated to be linked to instead of display on the registered URL (this is not the same as the Single NavBar feature), will result in PASS-L. Conversely, if the link is correct, but the coding is not, the site will still FAIL. Both criteria must be met in order to "PASS-L".

There are reasons why sites do not PASS, even when the code appears to be installed properly. See the section entitled "Why Sites FAIL" to learn some of the most common reasons why sites do not pass the automated checker.
