4.x login/sign-up pages redirect

[ag1266]

Hi,

I have just finally upgraded my site to 4.x. I use aMember for management of users as there are other components to the site that require sign-up. Under IPB 3.x it was possible to redirect the login and sign-up pages to external URLs i.e. the equivalent aMember pages, but for the life of me I cannot find this ability within 4.x. Does it exist? I see there are others using aMember. How have you got round this?
