Frequently Asked Question

Traditionally, [Usenet] has had frequently occuring postings which
discussed a [Usenet group]'s charter, the cultural expectations, and
answered questions that appear often enough that they become rather
annoying to the ''old-timers'' on the group.

In the case of Tcl, and comp.lang.tcl, you can find the FAQs easily without waiting for a post.  Take a look at [Larry Virden]'s excellent FAQ launch page at http://www.purl.org/net/tcl-faq/ .
