How do you write stuff in the F9, or quests section? Is there a special place in the editor (I haven't found it...) or do you have to use a trigger? I'm pretty sure it's the latter, but I thought it wouldn't hurt to ask.
As minikrampan already stated; it's done through triggers.
You can choose between 'Optional' and 'Required' quests. (They will show up on different sides of the Quest Window In-Game. Required = left, I believe.)
You can also choose the icon that each quest will display: using icon path ReplaceableTextures\CommandButtons\BTNAmbush.blp, just change this to change icon.
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
