L'associazione per la diffusione di \TeX\ in Italia, riconosciuta
ufficialmente in ambito internazionale, si sostiene \emph{unicamente}
con le quote sociali.

Se anche tu trovi che questa guida tematica gratuita ti sia stata utile,
il mezzo principale per ringraziare gli autori è diventare socio.
\medskip

Divenendo soci si ricevono gratuitamente:
\begin{itemize}
\item
l'abbonamento alla rivista \Ars;
\item
il DVD \TeX\ Collection;
\item
un eventuale oggetto legato alle attività del \GuIT.
\end{itemize}

L'adesione al \GuIT\ prevede un quota associativa compresa tra \EUR{12,00}
e \EUR{70,00} a seconda della tipologia di adesione prescelta e ha
validità per l'anno solare in corso.
