I would prefer that option. If tests needed to be reviewed, I would have been very unhappy about reviewing the test as ok, given that it is very likely to fail with most current ET optionlists. As such, I would prefer that we remove it for the release so that new users don't get worried about the test failure, and then implement something similar to the above scheme after the release. -- Ian Hinder http://members.aei.mpg.de/ianhin
