What is a "token expired" mean

[airlaird]

Sorry guys, I am not sure where to ask this question. Trying to upload pics in the classifieds. But my "token" has expired. What does this mean?

I'm almost scared to ask... Where are you getting this from?

It usually means you sat on a form (such as reply, edit post, etc ...) for to long before hitting submit. Most forums set this to an hour but I don't know about MUD. Probably a cache issue, try hitting refresh (F5) before you go into the upload pics form.
