Hi. We’re looking to create a platform where users can share or get startup ideas. I’ve been trying to use wix forum for that but since we are offering an idea-sharing platform, we want little modification to the wix forum. Like the ideas they share should have upvote option, we want to replace “Ask a question & Start a discussion” with “Share an Idea” and many more… It is possible to modify the forum? If no? can use corvid for the same?
Hi Ashish 
The built-in Forum cannot be modified! However it is possible to create the website you want using Corvid.
You may want to check out Wix Marketplace - It’s a place where you can find developers to help you on your projects. You can also contact me if you want to. (Links in profile).
