New Signature Limitations.

[Kosheh]

Also you haven't said anything about it (lol) but I noticed the signature separators are using the code I posted in the topic. Thank you, staff for quietly acknowledging my posts!

For some odd reason, the code I sandbox never quite shows up right for VGR, though (as there was a white bottom border) :/
After doing more tinkering though -- last time, I promise -- you kinda have to hack it together, making a 2px line while making a 1px solid bottom border, which then you'll get the desired effect.

Code:

<hr style="width: 100%; height: 2px; text-align: center; background-color: #DDD; border-bottom: 1px solid #fff;">

The SOLID is what makes the line actually appear. Give it a shot if you want - if it doesn't work, then it's fine.
I tested it out, and it looks pretty nice - even with 80% width.

For a mockup (kinda - used Firebug to debug) my sig has the 100% hr width and yours has 80% (the original size you set).
Both have the 2px line and 1px solid bottom-border.
