I was wondering how I could do the assist system by fishing for others? it doesn't really work when someone hits req.assist on me, all I get is a see through window with all the skills you can do

all you do is click on the fishing part so it turns blue, then sit there while the person fishes.

so I get the expeirence and they get the fish?

Yes, only if they can't, with their level, fish this fish :) If they can fish it, you won't get the exp.

couldnt you just use req assist to buy the eel for legends quest?or other items?or does it not work on stuff like that ya think :|

Doesn't work on quest items

It also doesn't work for entering guilds, just to make that clear as well. :)
