Not visible index ... i write variable after [ i ] .
Try highlighting some text in a message. Then, select the italic button. Notice that the code is wrapped in [ i ] and [/ i] (without the spaces) tags.
I guess we need to encourage people to start using j as a loop index, instead.
Of course, the idiotic rendering software could stop rendering italics if there is no closing tag.
Daniel: mark the code as code and it will show up properly
