## Main Question or Discussion Point

Firstly, where do I have to post if i have a question on LaTeX?

and here's the question,

$\vdash_{A}$

how do I make that subscript exactly below the line - on that simbol?

\mathop{\vdash}_{A}
will produce $\mathop{\vdash}_{A}$. You could also use \stackrel and play with sizing and spacing.
