   Format: MarkdownItexI gave Serving MathML a workout by copying a fairly intense nLab page. For the most part, it went without a hitch. I think it might get a little confused about adjacent ampersands or something. I don't know why some Unknown Characters. Note: It didn't like the asterisk for bullet points, so I had to put them in manually. Oh! Maybe I should have been using the HTML version of the editor instead of Visual. There are some other minor rendering issues, e.g. itex within bullet points doesn't seem to work.

   Format: MarkdownItexMy mistake. The asterisk DOES work, but the CSS replaced the bullet I was expecting with >>. When I used Visual to add bullets manually, it broke the itex. It is fixed now.

   Format: MarkdownItexShould probably link to it so everyone else knows what you are talking about: <http://www.math.ntnu.no/~stacey/Vanilla/WPMathML> I'm beginning to suspect that your browser sends random unicode spacing characters. What system are you using (OS, Browser)?

   Format: MarkdownItexAnd did you get that nLab material from looking at the "Edit" page of the nLab page, or from the "Source" view? I'm sufficiently intrigued by this behaviour that I might just fire up Vista myself to see if I can replicate it. The point is that when I copied out, letter for letter, what you'd pasted in then it compiled just fine. Somewhere in what you pasted is a hidden unicode character that itex doesn't like. That shouldn't happen, but it's something I've seen before quite recently ....

   Format: MarkdownItexI copied from "Edit" page. It could also be an issue with "Visual" vs "HTML" editor in Wordpress. I think I might have originally pasted everything with the "Visual" editor. Not sure though.

   Format: MarkdownItexReplying to Ian's question in the comments at Serving MathML and repeated in the nLab digest thread: I'm not sure whether or not the itex filter would work at wordpress.com. I've no experience with setting up something there and so don't know if one has sufficient control over things to make the necessary changes. In particular, one needs to be able to create a cache of the MathML (unless one can use the php bindings for the itex2MML library directly, but I doubt that that is possible). Also, there were a couple of validation errors which necessitated changing the actual wordpress code. Technically, these are bugs in Wordpress so ought to be fixed. However, as people using wordpress.com probably aren't bothered about serving valid XHTML, I don't know how highly they'd rate. I'd certainly be interested in the experiment being done, but I'm concentrating on the nForum at the moment (since that's a live installation) and there are a few upgrades that I've not ported over to the wordpress installation. In particular, the option to serve PNG, SVG, or MathML as appropriate would be nice but that's not over there yet. Is there anything stopping you installing wordpress on your own infrastructure? (Also, I apologise for not replying earlier to your question. I'm not really following the comments on the wordpress installation as it's not a "real" site whereas this one is. So when I spot a bug here, I do my best to fix it straightaway, but when I spot a bug there, I think "I must get round to that someday.". Similarly with comments, a comment here is more likely to elicit a response from me than one there.)

   Format: MarkdownItexLooking at the [differences between wordpress.com and wordpress.org](http://en.support.wordpress.com/com-vs-org/), I'd say that the answer was at best "Not yet" and at worst "No". To get the itex plugin working at wordpress.com, you'd have to request that the validation bugs be fixed (which, although low priority, is not an unreasonable request), that the mathmlised theme be installed, and that the itex plugin be installed. I don't know how amenable wordpress.com is to installing other themes or plugins and whether such suggestions are likely to succeed or not. No harm in asking them, I suppose!
