It seems that your are quite new to Hindi Wiki. Well if it is so, I formally welcome you on it. This is a free encyclopedia and you can edit it according to your wishes.
It revealed form your last editing that your browser doesn't have Hindi Support . When you don't have one, the मात्रा of इ comes after the letter and you will see it incorrectly. Your edit to the page गुरु गोबिन्द सिंह made the browser to display "correctly" for you. But for those who don't have these problems they will see it incorrectly. So I have change that to the original one. I hope it's not very harsh for you to taste the first bite of Hindi Wiki. Have a good day!
The developer team at Wikimedia is making some changes to how accounts work, as part of our on-going efforts to provide new and better tools for our users like cross-wiki notifications. These changes will mean you have the same account name everywhere. This will let us give you new features that will help you edit and discuss better, and allow more flexible user permissions for tools. One of the side-effects of this is that user accounts will now have to be unique across all 900 Wikimedia wikis. See the announcement for more information.
Unfortunately, your account clashes with another account also called TheSingh. To make sure that both of you can use all Wikimedia projects in future, we have reserved the name TheSingh~hiwiki that only you will have. If you like it, you don't have to do anything. If you do not like it, you can pick out a different name.
Your account will still work as before, and you will be credited for all your edits made so far, but you will have to use the new account name when you log in.
