It turns out that [strike] doesn't display properly in the mobile FT (mobile.flyertalk.com) ... and by "doesn't display properly" I mean "doesn't display at all" (i.e. words appear without the strikethrough).
This can obviously lead to confusion when a mobile user reads a post that uses [strike], because the struck-out word appears as normal text.
Is there a way to fix this in the mobile site?
