I've just had a look, made sure both newreply and newthread do have the alignment set to center, and checked the 'Message Area Width', which is set to 500px.
The Message Box is still aligned left. :erm:
Ah! I found the problem. It was in this bit of code:
Code:
<div style="width:$stylevar[formwidth]" align="$stylevar[left]">
I changed [left] to [center] and it fixed the problem.
Thanks a bundle for leading me to the right panels, Nutz. I'm still feeling my way through the Style Manager -- it's quite a big place to be searching for something in when you're new to it.
