So there is this button to check when you start adventure "Request Cooperation" and from what I know the only thing it does:

is showing this cooperation request in Guild Member list, which is not very usefull.
I was wondering if we could make something better for guild request that would be easier to access and here is my sugestion.

There would be extra option to choose adventure on your friends bar(Displaying number of active adventure requests).
And when you click on it you will see active Adventures cooperation request.

The Dark Brootherhood adventure hosted by currently online Szaryx.
Lakeside Treasure adventure scheduled to be started in 2 hours(can be difficult to read in my version) - as it's cooperation adventures.
There could also be marks to choose what do you need:
A) I require help - Emergency Case where you failed something in adventure and you need help to complete it.
B) Cooperation - I want to do this adventure together.
C) Lootspots available
D) I need to complete this adventure for quest/guild quest, but I am unable to/don't have adventure. - Other player may do this adventure and invite person asking for it.
Also if you clicked on one of those adventures you would be able to choose show details and there would be a little description from the player.
That would be really usefull for me.
