I don’t know if you have read the quite detailed forum rules in the form of the “Terms of Service” and the “Code of Conduct” or at least the shorter “Frequently Asked Questions about this forum”, but you don’t behave accordingly.
Maybe you look around here in the forum attentively and take an example of how the experienced users behave here? Often one learns well from the behavior of others.
Five directly consecutive posts are not welcome here, and you do not make friends with it, if you want to add something to a previous post, then you can add to your post, as long as no one has posted anything after that.
Furthermore, it would be nice if you instead of meaningless topic titles in the future meaningful and concise descriptions of your problem as a title to choose.
Before you ask a question, you should first use the search function of the forum. For your question about creating brushes, you will find countless detailed topics if you just search for it. This works with the help of the magnifying glass symbol in the upper part of the forum page! 
It’s also common here to ask your questions in the corresponding forum categories. You can read what each category is for in the category selector, above the Resources’ category you chose it says “Share and discover cool new brush packs, textures tutorials and other Krita resources here.”, how does your question fit in here? That’s right, it doesn’t!
For questions like yours, the category “Support and Advice” is meant, and the subcategory “Bundles and Resources Help” would have been the perfect match for your question.

Add/Edit: I did not even notice that here in the meantime has already been pointed out the many ways to find out about brushes. I edit in full screen mode.
