Man, not being able to change the primary tag at all sucks. I wonder if this will ever change

I had the same problem, i would like to know how it determines what main tag to post under and if it's possible to change.

I hope we can. I hope I didn't muff my intro post. But I guess that's the price of stupidity 😂

The first tag you enter in tag is the primary tag and cannot be changed. You can add #introduceyourself to the body so it will show up under that tag list.

Thanks for that, I was reading a few places that clued to this format and was going to try it.

You can not change the first tag, because it automatically becomes a category of your post.
You can freely change tags 2-5 to whatever you like.
A solution for this, if you realize quickly enough, might be to copy the post, delete the original and post it again in the right category.

@wellwild: This will help me. Thanks. But how can I delete a post?

Hi.I pressed enter after adding just one tag, now I wanna add more tags but I don't know how I do?If you get better solution tell me please.
Thanks

You can just edit the post then add the additional tags in the tag section. Just note you wont be able to change the initial tag set since that one is now somehow engraved in stone. And you wont be able to add more than five tags.
