I like your extension, "PSINoTocNum", but crashed my system. ?!?! any idea why? (I'm using mediawiki 1.6.10 + PHP4?) I used the code on your page and I followed your instructions from the link you sent...and the requireonce command in my LocalSettings.php cause the whole site to not resolve. I will look at it more closely tomorrow. I have written my own simple extensions, so I'm fairly sure I haven't overlooked anything truely foolish. also, once I get it to work, it would be nice if your extension could be made to do the opposite. i.e. turn off TOC numbers by default and "__YesTocNumbers___" in the extension. uh....full control of the style and prefix and suffix of the TocNumbers: like: "[#] -" which would generate: <span style=..myTOCstyleNums..>[1.2.3] - <span style=..myTOCstyleTxt..>Section Title</span></span> if you get the drift....i'm looking for full style control of the TOC same for the Section Titles in the Article if possible, what file do I define these in that is common to all skins? thanks ---- Frederik Dohr &lt;fdg001(a)gmx.net&gt; wrote:
