Setting rights?

Well i am new to Linux / OpenSUSE.

I have installed the HTTP-Server in YaST.
But when i want to edit or add files, i can’t,
because i dont have the rights?

Im logged in on the User i’ve created first.

When i want to edit or add:
(Its translated, maybe its some different)
The document is not safed, due to it is not able to write on srv/www/htdocs. Please check, if you have rights for this file or if enough Space is avaible.

How do i give myself rights to write/create/edit files in the Basicfolder?

Thanks for any answers

If this is just your server, you are the only user and you are just playing around, the easiest is to make the folder owned by you. As root:

chown kenyoku:users /srv/www/htdocs

Hmm when i type this into the terminal i get:
chown: changing the owner of srv/www/htdocs. This operation is not allowed.

Any other ideas?

You have to it as root. Do:

sudo chown kenyoku:users /srv/www/htdocs

I hope you remembered your root password.
