How do i start a engaging discussion?

If you have read discussions here you will see they are on many topics. Just choose any topic and I am sure there will be many who will want to interact with you. But it does not happen overnight that you will get several on your post. They will slowly catch up with you.

To start an engaging discussion you should write about what you know. Have you read discussions by others here, they can be about most anything. Then after writing, go visit with people and get to know them so they know you are here. It's best to write more than a few sentences, as many members won't pay short discussions much attention.

i wouldnt know until you start one, i guess. they would rather post it under their profile i bet.

Don't write the same thing over and over Write about things you enjoy. Posts with images are more interesting. Edit your work and find an interesting title that might bring people over to read the post.

It may differs from people to people
