Hi,

That's the question. With only a URL we can't decide, to take the old or the new way.

Is it useful to support the old way (until the end[tm])? What will we do in the future, if we found another service/way to enable TeX-support? Isn't it a barrel without ground?

Currently, I prefer the following solution:
bbcode_tex can be enabled/disables (i.e. set to 1 or 0); per default, the option is disabled
bbcode_tex_uri is a new option to define the URI of mathjax (default value is the external service)

Depending on the tex option bbcode_tex, we add the script defined in bbcode_tex_uri (at runtime). If the option is disabled, we don't add any further script.
