What others have stated.
When in game, you can message them using;
/msg *username Hi? are you there for xxx item / level / mods?
by using the * (asterisk) in front of their username you will be able to know if they are online and also what character name they are using.
Also, if they are not online, you will be informed.
If they are online you can even check their last action in game, they maybe on another window, in another game, maybe checking the forums... so with your first message, and they are online but not replying, you can use their character name:
/who JoeDiggle
This will show length of time in seconds ... last seen 65 secs ago (something to that effect).
Hope this helps
EDIT: forgot to add... if they are online and have replied to you, you can just type:
/r oh hey, I am putting item on MP now... Sword, 55 lvl, 102 ee @ 500 fg.
when you have put it up. reply again.
/r up now
