I know that people don't necessarily read the forum rules, but we have a limit on the size of signatures. It's to prevent strains and ruptures to the ligaments of scrolling fingers.
A couple of people, on being approached, have been good enough to reduce their signatures, but there are quite a few more that exceed the limit. Please read through the quoted rule below and see if this applies to you.
11 Member signatures should contain images with a combined size of no larger than 128px high and 1024px wide. Please limit any verbiage to 5 lines of text in a reasonable font size/style (as determined by the staff). Note that valedictions such as "Cheers, memberxyz" are not included in the 5 line maximum. While animated signatures are acceptable, please take care not to annoy others with flashing banners or other images that distract from the discussion.
