There are two sections from the Posting Guide that may be relevant:

---begin--
Questions about statistics: The R mailing lists are primarily intended for questions and discussion about the R software. However, questions about statistical methodology are sometimes posted. If the question is well-asked and of interest to someone on the list, it may elicit an informative up-to-date answer. See also the Usenet groups sci.stat.consult (applied statistics and consulting) and sci.stat.math (mathematical stat and probability).
---end-----

Frankly I would not considered this question to be "well-asked" but anyone is free to dispute this or to take on the task of asking clarifying questions. 

A modern update might add to the Posting Guide in these more web-centric times, the CrossValidated.com site. https://stats.stackexchange.com/search?q=latent+variable+roc

(Those newsgroups are basically defunct.)

---begin--
	• No HTML posting (harder to detect spam) (note that this is the default in some mail clients - you may have to turn it off). Note that chances have become relatively high for ‘HTMLified’ e-mails to be completely intercepted (without notice to the sender).
---end-

One of the effects of redistribution by a mail-server is the removal of the identity of your mail-client, so advice about that concern can only be "RTFM".
