Have you tried Latex? I think inserting characters should be OK but it might depend on how you want to format them. If you have problems inserting then I would also try hoghighting and using the ‘code’ button on the editor or even trying it with the HTML editor…

Also y want ajax Reply :S

Ajax makes good add-ons…

AJAX = Active Java And XML… without getting into the specifics, adding ajax output to the available forums would allow for better thirdparty plugin integration, and possibly SPF specificly developed widgets, in the veign of BuddyPress and bbPress projects which have taken on a new life of their own.

Actually it stands for Asynchronous JavaScript and XML.

AJAX is a technology not a 'thing'. We don't use it in SPF but do use a large amount of Asynchronous HTML and HTTP which does the same job but is easier to code and maintain. It is used all over the place and we are constantly taking advantage of it with new features and recoded existing ones.

The 'Quick Reply' from the admin bar for example uses this technology. Version 4.1 converts the entire admin interface to use this technique.

But the whole point of tools like AJAX and AHAH is the specifics – where to use and where not to use.
