Randy,
Please be aware that the CVS HEAD is very different from OACS 4.6 as all the development work on OpenACS not belonging to OACS 4.6 has been committed to the HEAD. OACS 4.6 is on a seperate branch which has not been merged with the HEAD yet. The CVS HEAD contains work that when merged with the 4.6 branch will become the basis for 4.7.
Your installation of the CVS HEAD with PG 7.3.1 is cutting edge but certainly not OACS 4.6.
You can log individual bugs in the OpenACS bugtracker (https://openacs.org/bugtracker/openacs/). Make sure that you log the bugs with the right version. Bugs found in the CVS HEAD should be logged as version 4.7.
Bugs encounterd in either the 4.6 tarball or the 4.6 branch with PG 7.2.x should be logged as version 4.6.
There is no point in logging bugs found in the tarball or the 4.6 branch in combination with PG 7.3.x as 4.6 doesn't support PG 7.3.x.
