What do the little envelopes and yellow cans above messages mean?

They are new, aren't they?

Okay, I've sussed the envelopes, but what are the cans?

they take you to the poster's Profile page, where you can put pics, info etc

Thanks

janitor love, the cans are only visible if the poster has created a profile. Put your arrow over the icons and they tell you what they're for.

Erm..isn?t it a clipboard rather than a can?
