@avatarashakti Hello, and welcome to Qoto.
Enjoy the network and all it has to offer. If you are new to using Mastodon, there's a good guide here: https://lifehacker.com/a-beginner-s-guide-to-mastodon-1828503235
We also have another new users guide, posted here : https://write.tedomum.net/rgx/suggestions-and-guidelines-for-new-users-written-by-mastodon-art-administrator
Casey Rollins made a video to explain the Fediverse, here :
"I made this video awhile back to help explain how the #Fediverse works."

Any question, just ask, and someone will try and help out.
** I noticed you tried to use the html code to verify your URL in the profile -- but the idea is that you include that snippet of code inside a webpage that you own and can edit. Then enter that page's URL in the Preferences here.
If the page you linked to has that little code strip, it will verify you own the URL and show a green check-mark in the profile.
Have a good day!
