Drupal 7.x

hello,

I am trying to uninstall drupal 7 from a linux server; there is very little info about this uninstall procedure.

i have used the following link http://jamaco.org/wp/2010/08/26/removing-drupal-from-your-system/

which gave me enough information to stop and remove drupal and it's database;

NEED HELP USERS ???
Hi users i have installed drupal through softaculous , now i want to add
custom logos and avaatars to my page ?? can any1 tell me how to do this???

I installed Drupal 7 core, themed with Danland theme and used Superfish menu.

1. Now, everytime I do search on the site, the search result page would not show the top navigation menu bar(which is inside superfish block) where all links are eg. Home | Services | About Us ..etc.. I tried almost all things from google finding.. It's not working and took so many hours already.

2. And then when I search some keywords, the URL shows something like /search/node/(keywords)

I wish I could have control over that search/node/. The word 'node' be some alias.

I'm trying to develop my own module and everything works fine.
But after some time passes, I sit back on the computer to find this error message appear out of nowhere...

Hi all,

Hope someone can help me here, with my following problem.
What I'm trying to do is that a specific user role can create users and assign them to a user role I approved. So they cannot create roles that are admin or other high user roles.

Currently I'm using Drupal 7 and tried already something. In the permissions section I can select 'Administer permissions' and 'Administer users' but when I enable these the user role can also create a admin user what is not really what I want, or they can edit ALL the users (including admin).

I am making a Real estate website where people can come in and post their real estate listings. I have looked through different modules Lists and few others but they are all for drupal 6, I was wondering if there are any modules like these for drupal 7.
