I was going through the "How To" section of the forum and found that many of the posts had a "56K Warning." What is meant by this?

 

that there are lots of pictures and a 56k dial up modem would take forever to load those.

 

A "56k Warning" is a nice way of telling someone they might stand a chance of a black hole opening up inside of their home if they use dialup and try to access a site bogged down with images or videos.

Basically if you're in that 16% of people who use dialup, you need to watch out for these.
