I have nospoof turned on to see the names of those notorious posers (like myself) who often forget their names in poses. I noticed that when another player is on from the web portal, their emits do not show up with an %% Emit from : tag to the people who are playing from a client.
Players who are playing from the client who @emit will show an %% Emit from : message to others on the client as expected.
Players who are on from the portal should generate an %% Emit from : message for those who are on from the client.
