So replying directly to other users is most easily done by pressing the quote button. As you can see above, I have done that to your previous post and you probably got a neat little notification for it.
If you want to quote a specific portion of another user's post, you use your mouse or touchpad to highlight the part that you want to quote. You will then get a little prompt to quote that selection. Click it and it should let you quote the highlighted text.
I see you already know about tagging. There's no real defined etiquette to it per se and users generally apply its use to whatever they find comfortable. If I were to offer a recommendation, generally I'd say it's better do it when you want to call a user to a thread -- usually in status posts, blogs, or silly threads in forum lounge/forum games -- or you're having a discussion with another user and your response doesn't relate to something they've directly said.
Hope this has been helpful.
The PoniArcade section still exists, but is now under the "Archives" section.

Unfortunately, this does mean what you think it does. PoniArcade is no longer up and running sadly and hasn't been since around 2022.
Hi @Brony4ever36 I've moved your thread to site questions. The welcome plaza is for introducing yourself.
I'm unsure if you want to create a club in the dedicated clubs section or a fan club in sugarcube corner. Let me know which one it is.

Also, what character do you want to make a club for?
