Thread:Project:Support desk/Except a heading from TOC

I'm using these: MediaWiki: 1.17.0; PHP: 5.3.3-7+squeeze3 (cgi-fcgi); MySQL: 5.1.49-3 at http://pea.vesperto.org/

My question is: How do I supress some headings from showing up in the TOC, and otherwise keep their usual behaviour? I need it for this page, where the headings from the transcluded template should not show up the the TOC of the pages including it.

Thanks for your time!
