You should not start just another forum. Instead of that you can write blogs in a simple manner with deep details there are many blog sites too but most of them are not providing solutions in details.
Also you can keep both Blog and Forum.
Hello ankit10,
You got a point that there are a lot of hosting related forums however not many of them provide any board to help peoples for free with their problems no matter what hosting service they use (This is as far as i know only). As for blogs,yeah blogs are a good way to help others too however most of peoples do not even understand how to follow a tutorial or they get unknown errors during the process. That's why is way better to use a forum where you hear others opinions on the issue then a static blog post. As for the recommendation of blog + forum together thats a good idea too i will note it however there are no plans for that for now. And there will be even more stuff added to this forum very soon so i would recommend you to join and support us until then.
Best regards!
