## Mailing lists
For questions, answers, feedback and other general discussion please
join the [mailing list][mailing-list]. Changes to the DCE/RPC source
code will also be posted to there.
## Reporting Bugs
If you find a bug or have an idea for an enhancement, please open
a [Trac ticket][trac].
## Projects
There a lots of interesting project to work on in DCE/RPC. Here
are some ideas:
* Clean up dce_error_inq_text to use error_status_t and
dce_error_string_t parameters.
* Not all errors are in the message catalogue, eg.
rpc_s_protseq_not_supported is missing. Need to find and
catalogue all errors.
* Fix the IDL compiler so that [in] reference parameters are
declared with the const qualifier.
* Add support for [out,unique] parameters as used in the spoolss
protocol.
* Add launchd (Mac OS X) and systemd (Linux) support to rpcd.
### Projects specific to Mac OS X
* Implement a ncacn_mach transport for local RPC on Mac OS X.
* Add instant-off support to the RPC runtime.
* Replace the DCEThreads runtime with [libdispatch][libdispatch].
