UPD: premades will not be announced while in an instance

What does this mean? Does it change anything in Raid premades?

On the setup tab you will see a option which says "announce premades".

When announce premades is enabled, oQueue will print the name of new groups into your chat area. Infront of the new groups will be the purple diamond symbol.

This change forces oQueue to not announce these premades, when the user is in a instance or raid.
