I have "
two shoes that don't match"...? I assume that is an English proverb. But I do not know what it means, Neal.
I never used pics, only coloured text. I never got any pics working in signatures. I change colour when I changed the text, which I do often: whenever I remembered or stumbled over a new - or new old - quote that I like.
On the issue, there should be size limits. Since it is about scrolling a thread, it mostly matters regarding vertical dimension, and thus I think a sig, may it be graphic or text, should not be thicker than 3-4 lines of text. Many, if not all forums I monitor, have limits much tighter handled than over here.
In the poll, option 4 my choice.
