Hello,
This note is to announce that after some time off, the Boston area DITA
Users Group will be starting up again in 2009. To get things started, we
have created a new group Yahoo, so that we will be in sync with and
searchable by users of the many other Yahoo DITA lists. If you are
interested in joining the DITA Boston Users Group, please visit this page
for sign-up info.
We will soon be sending a survey to that list with proposed meeting topics,
so please sign up in order to help us decide what to feature. We will also
be looking for companies willing to host a meeting; if you already know you
are interested in hosting, please join the group and send a note to
ditabug-owner (which will go to me as well as to Liz Augustine and Lee Anne
Kowalski).
