I already have amember installed and integrated with my users in vbulletin. I'm now adding a login section to the joomla section of my web site. Can I integrate amember with this also so that all three work with only one login?
Yes, but user will be logged-in to Joomla and Vbulletin only if he uses aMember login form. All users changes made in aMember will be replicated to both Joomla and Vbulletin.
When I set up the vbulletin integration I was able to link the Login link in vbulletin to go directly to the aMemeber login page. Can the same be done with Joomla? So that someone wouldn't be able to even get to the Joomla login anymore, but would go directly to aMemeber?
