LAMP users, groups, permission and a lot of confusion

https://bbs.archlinux.org – I do not understand all the fuzz with Linux users and groups, nor do I believe I will ever do so, but that is usually alright, as it usually do not affect me. What I can not do as a regular user I can do as root.However, I've just been setting up a LAMP server, so that's another story.I've tried to add my self to group http, and I do believe I've succeeded, so it's a bit confusing as using the groups command without parameters do not list the http group, but with my username as parameter it does. Maybe I need to restart? (that would be weird)In any case my user do not (HowTos)
