I picked up a whole bunch of Leves yesterday for fishing, logging ect. but then went to bed before doing them. When I woke up and started playing FFXIV, I was in a party and did about 6 Leves that belonged to someone else. After he went to bed I wanted to do the Leves picked up last night but they are all greyed out except for one. What causes them to be greyed out? I didn't do a single one of them. And I read that doing other peoples Leves has zero effect on your own

Besides that I got my Botany and Marauder up a little bit so I'm happy. Need to work on crafting next so I can replace all my level 1 gear

Last question: If a shirt says "Gathering+5" on it, what does that actually improve?
