We have tried installing two Mediawiki extensions, FCKEditor http://www.mediawiki.org/wiki/Extension:FCKeditor_%28by_FCKeditor_and_W ikia%29 (Wikitext version) and CategorySuggest http://www.mediawiki.org/wiki/Extension:CategorySuggest . In both cases they caused format loss in pages that used text indenting, and we've had to remove them from our site since some groups do a lot of indenting, and they really need to in order for their text, code snippets, etc. to make sense.
In most cases the indenting is done using leading spaces, which seems to be the recommended way with Mediawiki. <PRE> tags aren't really recommended and some formatting can't be done inside them, but they do seem to maintain the indents better than just leading spaces. We've also had some people doing indenting using various levels of colons (:), and those are also being lost.
Have other people run into this, and are there any workarounds? Both of these extensions would really be a benefit to us if we could overcome this loss of format issue. I figured when we ran into the problem with CategorySuggest that maybe it was just a fluke, peculiar to that extension, but now that it's two of them I'm wondering if this will be a common problem, and that other extensions we try will also cause format problems.
Thanks, Pat
