If you want to contribute code or ideas, write to the AUCTeX developer mailing list (auctex-devel@gnu.org). And in the rare case of finding a bug, please use M-x reftex-report-bug RET which will prepare a bug report with useful information about your setup.

There are also several Usenet groups which have competent readers who
