# Technical Support

This information applies to the open-source product only.

Please read the Conditions of Use.

The open-source Saxon-B product comes with no warranty and no formal technical support service.

If you have questions, however, you can usually get an answer by raising them on the Saxon discussion list at http://lists.sourceforge.net/lists/listinfo/saxon-help.

Once registered, you can post messages to saxon-help@lists.sourceforge.net.

If you hit something that looks like a bug, please check the known errors on the Saxon project pages at SourceForge. Also check the list archives. Please don't enter the problem into the bug register until it is confirmed as a bug: it's easier for everyone to search for real bugs if the register isn't cluttered with problems that turned out not to be bugs at all.

If the query relates to the XSLT/XPath language rather than Saxon itself, it is better to use the xsl-list: check first that the query isn't already covered in the FAQ. Other useful sites for XSLT information are www.xslt.com, www.xmlsoftware.com and www.jenitennison.com.

Help forums for XQuery are less active at the moment, for details see the XQuery home page at http://www.w3.org/XML/Query
