Guild Wars 2

Sup X /Sup

And

Sub X /Sub

Rarely work. Are there certain factors that prevent the code from working, just like you can’t apostrophes in conjunction with italic

I can’t use apostrophes in italics? I didn’t know

However, I’ve never gotten sub/super scripts to work. The literal examples from the more pasting and formatting options seem broken:

• The most common use of E[sub]3[/sub] is for fuel.
• Einstein is famous for his E=mc[sup]2[/sup].

Unfortunately, the forum code was maintained by a 3rd party provider who is no longer available. The only way for ANet to change or improve it is to replace the entire current system. Given that things work well enough, that seems like an unnecessary expense.
