Aside from the specific topic at hand, I agree of the whole site change. I am coming from a huge forum that does not allow images/html in sigs, avatars, and perfers if people use image thumbnails or at least warn of pictures in posts for 56k, I'd like to see changes too.
Staring at the huge image sigs is definitly a turn off when trying to read a thread, especially in longer threads where the same people are posting.
Rather than change the entire site though, what would be probabally more friendly is taking the "Topic review" code, making it so it displays sequential, and provide that via a seperate link in a collumn on the thread listing page. I think everyone would be happy
The only other thinng would be to require tags in threads that have a lot of images that are not thumbnails. [Big Pictures] [56k No Way], etc... just as a "courtesy" measure.
I'd also like a way to use the "small" html tag or some bb equivilant so text in sig can look nice and neat rather than regular text. That way, people that have lots of text in sig can make it smaller if they want.
