Less Wrong is still under construction. Please post any bugs or issues with Less Wrong to this thread. Try to keep each comment thread a clean discussion of each bug or issue.
Requested features... sure, go ahead, but bear in mind we may not be able to implement for a while.
That looks like a reasonable workaround. With Markdown you can embed images so your image above can be embedded directly:
I've also added a feature request for jsMath.
Ah, I didn't know you could embed images because it wasn't in the help. Would it be a good idea to put a link to a Markdown tutorial at the bottom of the table that pops up when I click the help link?
