Thanks very much for your email.  Please make sure to send all questions
related to ACE+TAO to the appropriate mailing list or newsgroup, rather
than to me directly since I travel frequently and often don't have ready
access to email.  See


for more info on how to access these resources.

In addition, to ensure that we have proper version/platform/compiler
information, please make sure you fill out the appropriate problem
report form (PRF), which is in


Make sure to include this information when asking any questions since
otherwise we have to "guess" what version/platform/compiler/options
you've using, which is very error-prone and slows down our
responsiveness.  If you don't use the PRF, therefore, it is less likely
that someone from the core developer team will be able to answer your
question.  Naturally, we encourage and appreciate other members of the
ACE+TAO user community who can respond to questions that they have the
answers to.

Please note, moreover, that the DOC group at Vanderbilt University
only provides "best effort" support for non-sponsors who are using the
latest release, as described in


Therefore, please make sure you are using ACE+TAO+CIAO+DAnCE x.4.6
(i.e., ACE 6.4.6, TAO 2.4.6, CIAO 1.4.6, and DAnCE 1.4.6), which you
can download from


If you need more "predictable" help or need help for earlier versions of
ACE+TAO please see


for a list of companies that will provide you with ACE+TAO commercial

Thanks very much,
