ok so when you write a line

you can highlight it it first

then with the highlight still on there,

you go and click on the little quote icon

and then two things will pop up on either side of the text [QUOTE] /[QUOTE]

but they shouldnt be side by side they should be like bookends around the highlighted part

like this [QUOTE] blablablabla / [QUOTE]

and then the result would be that you hit "post quick reply" and it looks like this

hope that works
