To be honest, I think signature rules could be rewritten far more simply, as follows:
No user's signature may either exceed 150 pixels in height or be so wide as to stretch a normal thread, as viewed on Windows XP in Internet Explorer fullscreen with default settings at a resolution of 800×600 pixels. All images in a user's signature combined may not total more than 100 KB in size. The heights of certain convenient things are as follows:
- One line of size-1 text is 12 pixels high.
- One line of default (size-2) text is 16 pixels high.
- One line of size-3 text is 18 pixels high.
- One line of size-4 text is 22 pixels high.
- One line of size-5 text is 29 pixels high.
- One line of size-6 text is 38 pixels high.
- One line of size-7 text is 61 pixels high.
- An attributed quote ("[quote=...]text[/quote]") adds an extra 68 pixels, and reduces the text inside it to size-1.
- An unattributed quote ("[quoe]text[/quote]") adds an extra 41 pixels, but maintains the size of the text inside it.
- Userbars are generally 19 pixels high.
This means that, for instance, you could have: a single image 150 pixels tall; a 100-pixel image and three lines of normal-sized text; a two-line attributed quote and three lines of normal-sized text; nine lines of normal-sized text; or twelve lines of size-1 text. Remember that if you're at a high screen resolution, there may be more lines than are displaying on your screen, since the standard is 800×600.
Civitates may use an additional 16 pixels of height, to acknowledge patrons and other "relatives" only. Patricians may use a further 32 pixels of height, to acknowledge clients and other "relatives" only.
This is, of course, the extremely consistent and logical solution, me being me. Whether it's too confusing is debatable, but it doesn't significantly increase the current limit (a 100-pixel image plus three lines of normal text is 148 pixels), and it allows more reasonable flexibility than the current rules. Plus, you no longer get to have more text if you just take a screenshot of it!
(I chose the browser, OS, and resolution I did, by the way, because to the best of my knowledge, all three are the most common. Archer or Mithras probably has access to the exact stats for visitors here.)
Anyway, what follows is some more specific points I have issue with.

Who exactly is going to write this semi-automated filtering script, and what upload filters do we have (on signatures, not avatars)?

Suggested clarification: "The total size of a user's signature may not stretch the thread as viewed on Windows XP in Internet Explorer fullscreen with default settings at a resolution of 800×600 pixels." Screen stretchiness can vary from browser to browser and depending on settings, and 800×600 pixels is more common than 1024×768.

Members can count. Leave out the userbars; they're just a fad. Also, make it clear that it's 100 pixels collectively, not 100 pixels per image, and add the aforesaid proviso (because images stacked horizontally may have a linebreak inserted between them at lower resolutions if they're too wide). So "All of a user's signature images together may not exceed 100 pixels in height as viewed on Windows XP in Internet Explorer fullscreen with default settings at a resolution of 800×600 pixels."

Leaving this most ridiculous rule in kind of defeats the purpose of revamping these rules in the first place. Drop it entirely.

[list]Users who use any signature image(s) of any allowed size will be limited to three (3) lines of standard sized text in their signatures below the signature images.
I've always objected to this. Look at this screenshot:

As you can see, six lines of text take up 96 pixels vertically. Three lines of text take up half that much space. Equating 48 pixels of text lines to 100 pixels of image is ridiculous. See my proposal above.

This is entirely unnecessary. Giving Patricians an extra three lines is already excessive; giving staff members another two or three "to assist in conducting site business" potentially makes signatures unreasonably long.

First of all, nobody uses these, and they're viewed infrequently compared to signatures, plus they're meant to be more expressive, so there's no reason to restrict them so much. Second of all, there's no reason to give anyone larger personal images than anyone else. Allow anyone to upload a personal image of up to 600 pixels wide by 1200 pixels tall, up to 512 KB in size, say.
