The 'postOther' command has the following interface:
'postOther', relative breadcrumb [, hostingUrl][, optionalVariables]
The postOther command sends a "relative to its parent breadcrumb". This means that if you submit Video/Play after a pageview breadcrumb of Home/Category the effective path is Home/Category/Video/Play. If you send the same path Viedo/Play after a pageview breadcrumb of Home/Search the effective path is Home/Search/Video/Play.
Example of use:
// Track a popup dialog containing membership invocation. This dialog appears on any page on the site. We'll call it "Get membership" $netminers.push(['postOther', 'Get membership']);
