Hello there,
As a new member in this forum and wish to share and gain some knowledge. I am looking forward to create my own discussion to resolve my query and gain some knowledge though I have taken part in various discussion which is definitely helped me a lot.
Also in what category should be taken depends on what factors?
Thankyou 
in advance.
Hi and welcome @Arthur,
What is the query you are trying to solve?
And then it comes to categories I would say just use your best judgement.
Best,
mj
Hello @Arthur - welcome to the OpenSearch community! Each category should have an “About the ” post at the top describing types of topics that would be relevant. If you have questions on where something belongs, or, if you post somewhere and it needs to be moved to a more relevant category, reach out and one of the admins/moderators can assist on that as well.
