Changing the name of an admin or any other user shouldn't mess up anything. (All "posted by" info and other references to user name will automatically reflect the new name.) User names are just there for our human convenience; the underlying User ID number is what Drupal is concerned with.
Is search on Drupal.org not turning up what you want – or (as happens at times) is the site's search function not working at all? Let Google help out: give Google your search terms, followed by site:drupal.org . Voila!
Read up on a few more search tips.
If you're wondering whether a given site was made with Drupal, Is This Drupal? will take an educated guess based on header and file info. The creator can't guarantee accuracy (a given site may use tricks to hide its tech identity), but this is an interesting tool to have on hand!
Want a quick redirect, without manhandling system files? Just use the core Path module: on the "URL aliases" form (/admin/build/path), complete 'Path alias' with the path you expect visitors to use, and complete 'Existing system path' with the path you'd like to send them. 'Path alias' can be an existing system path; Drupal will still treat it as an alias and send visitors to your specified path.
You've logged out as admin, and realize there's no login block on your site... You're locked out! It's the #1 newbie emergency, with daily pleas for help appearing on the drupal.org forums!
Relax; getting back in is simple. The path <your domain>/user will always provide you a login form. (Make that <your domain>/?q=user if you don't have "clean URLs" enabled.) You're back in action.
The Book module creates "Printer-friendly version" at the bottom of Book pages. If you hit that link from a page with child pages, Drupal creates a printer-friendly page from that page and its child pages. If you hit the link from the Book's top page, you get the whole book in a single page!
Got unexpained "access denied" troubles keeping people from your content? Go to admin/content/node-settings, and try the 'Rebuild Permissions' button.
If that doesn't work, see other ideas for access denied for visitors and access denied for admins.
Don't give a theme and a node the same name. Conflicts can occur.
An obvious but important tip: When installing a new module, be sure to check for READ ME files or other instructions! It's easy to forget that not all modules are simple "plug and play"; some require special preparation, such as modifications to the site's Theme, to work their magic.
Remember, modules often make changes to your ste's database, its very "DNA". Take their installation seriously: read modules' instructions, and back up the database before installation too.
Got a menu item that's acting oddly, such as an admin-only item that's showing up for all users? On the admin/build/menu form, see whether the offending item has a 'reset' link. If so, clicking it may solve the problem.
If you disable the Statistics module, you'll lose the Popular Content block.
The basic concept of a CMS (content management system) like Drupal, is that you don't create pages as a whole. You create bits of content and other elements (nodes, blocks, header, navigation...) and you configure the CMS so that it puts your page together on the spot.
It looks to me as if #1 and #2 are handled by general Drupal permission features. #3 should be...
