Fun fact, this thread directly goes against the forum rules!

Please do not create “personal best” or “personal record” threads. There is an Accomplishment Thread where you can share your records with the community. Otherwise you can utilize your signature to post your records.
A lot of users add to their signature, but you can also add them to your Speedsolving.com profile. Go to your profile, then click on the Accomplishments tab, mine is shown here: https://www.speedsolving.com/members/pjk.1/#record
You can then add your PBs there and update them as needed. If you added your official WCA ID to your profile, you will see an "Official Results" tab which will show your official results in your speedsolving.com profile. I encourage all members to add their PBs to their profile. There is also a leaderboard to view your rankings on the site (we do need to moderate some of the fake entries - if you add fake entries we will remove them and ban your account - we do not tolerate this - the goal here is to simply display your real PBs on your profile): https://www.speedsolving.com/rank-board/?key=1
