Lots of plugin available just need to search for them in WP plugin repo.
Ok this will be added. AnsPress will look into child theme then parent theme.
Hi Changing username completely on only need to change users slug? 1- for username you need “Username Changer” plugin. (It’s good but this way (changing username only) is not a safe way) Username Changer is a simple plugin which allows administrators to change usernames of users on their sites. Additionally, if the user display name matches the username, it is updated as well. 2- for username slugs (this is a safe way), In my opinion, the best way to this issue is testing “Edit Author Slug” plugin. I used it in one of my sites and it is very useful. You will be able to change all of users slugs BUT if AnsPress and it are compatible (I think they are compatible because “Edit Author Slug” and BuddyPress are compatible ). please check it and give Feedback. GOODLUCK
There are lots of plugin available for that, use them to rename user_login in your site.
Check in AnsPress options -> permission
Yes. Just add [anspress] to the page you want this Q/A forum to appears. This is independant of the rest of your website and once logged, your visitors will be able to use it. This is a plugin and not a theme, so you can use it with the theme you want.
Thank You Rahul (it give me an idea for future update, when typing your name, let the system complete it and link it to your profil or like twitter if we could use @Raluh_Aryan for exemple)
