Hi @guuduop and welcome to Hive as I see you're new. Thanks for sharing these facts with us, it's interesting and also educative. I'd like to suggest Hive Learners community for these type of topics next time s OCD community is for topics that don't fit in any other community.
I see you're new on Hive, so let me drop you a few suggestions to help you navigate better on our platform.
We have different communities on Hive and we're encouraging users to post in the right community based on the topic of the post.
Here's a guide I put together to help you learn about how communities work and why you should use them -> Communities Explained - Newbie Guide. I also put together a list of communities, which is not complete, there are much more communities on Hive, but it will help you get started.
Once you posted your post in the right community, you can then cross post it to OCD community. Here's a guide about cross posting.
Please don't delete any post with the purpose of reposting it in another community as that can be considered abuse! Leave this post here, you'll get it right next time.
Thanks bro for your kind information :-) . I have to learn a lot of things in hive , there are several friends who helped me out , am learning something day by day .
