I'm not sure if it is really possible to centre text on Horseisle, because i have tried doing it. I would ask a Mod if i were you. HOWEVER if you really want to centre text right away, i would do the following: space space space space BLAH BLAH BLAH space space space space space space space space space BLAH BLAH BLAH BLAH BLAH space space space space space space space space space BLAH BLAH BLAH space space space space space So pretty much, all you're really doing is just pressing the space bar until you get to the spot where you want the text.
If you ever need help on Horseisle, I would recommend the Help Center on the website.
You can center your text by Copy and Paste this: <center>ENTER TEXT</center>
