In the quest of building a mod,
if someone logged in from hubzilla node 'email@example.com' visits a hubzilla mod page at 'firstname.lastname@example.org', where they can manage their own site-specific information (ie, not their profile, but information on app.com), what's the best way to identify them when they return?
I see local_channel() which return an integer value. But I'm not sure that's the right idea?
$channel = $a->get_channel();
