It is a sticky because it is informing you, as an Ubuntu user, where to get the best information you can get for setting up your Ubuntu, or any "family" member, install up.
Expresions of delight or gratitude are certainly not disallowed.
It is, by the way, a great site. I haven't logged in for years, no longer an Ubuntu user, but they will be needing help updating the site for the next release fairly soon. You might try setting up an account so you can help edit in any changes that are needed for that next release, particularly if you are using the Ubuntu-testing version right now.
Potentially, this thread could be very beneficial provided it is organized by Ubuntu version number (13.04, 14.04. 15.04 ...).
Ubuntu, over the years, has undergone numerous revisions that make some the older posts "obsolete".
Additionally, some of the older links provided in the posts are now "broken".
In posting, the website noted in bright red letters: " Please note that this thread has not been replied to in over 6 months. Please ensure your reply is still relevant and timely." Obviously that raises the question of whether this thread should be kept.
Should this thread be kept, I would suggest that the posts (in line with being a Ubuntu guide) reference specific (topical) on-line documentation.
My thanks to ArrayBolt3 on askubuntu for his notation

In Ubuntu 22.04, the feature that usually populates the boot menu with all of your operating systems is called os-prober. For security reasons, os-prober was disabled by default in the bootloader included with an early alpha version of Ubuntu 22.04 (GRUB 2.06), which made it so that the other operating systems on your system were not detected. (Source: https://www.gnu.org/software/grub/manual/grub/html_node/Simple-configuration.html #Simple-configuration Search for "os-prober" on the page to find the relevant info.)
To get your other operating systems to show up in the boot menu, you can re-enable os-prober. This will come with some security risks (for instance, if you have a malicious drive plugged into your system, and something like a kernel update causes os-prober to be executed, the malicious drive could try to exploit a security vulnerability in your system), but for many users, it's not that big of a deal, and the benefits outweigh the risks.
To re-enable os-prober, open a terminal with Ctrl+Alt+T, and run sudo nano /etc/default/grub to edit the grub-mkconfig configuration file. You will be asked for a password before the file opens, since you're opening it as a root user. Once the file is open, add GRUB_DISABLE_OS_PROBER=false to the file, press Ctrl+S to save, and Ctrl+X to exit. Finally, run sudo grub-mkconfig -o /boot/grub/grub.cfg to regenerate your GRUB configuration and boot menu, then type exit to leave the root shell. You can now close the terminal, and you should be done!

Reason: Ubuntu had blocked os-prober
