New accounts every time for Wiki projects?

Do I need to create new accounts for every wiki submission I run? Can I use the same old accounts for multiple submissions? Also, do wiki sites only require captcha for creating accounts or for submissions as well?

There are many wiki software available, you can be use but manually submission is best option, i will suggest to you before submission read this en.wikipedia.org/wiki/Wikipediaolicies_and_guidelines

In wiki sites Usually we post content in profile page or we can create new pages. But all wiki sites do not support this. In some wiki sites you can only edit in profile page and you can not create any new pages and in some wiki sites you can not edit profile page , but you can create new pages.
