Guild Wars 2

I joined a spontaneous party the other day and the other players were pretty solid. I had hoped to track them down later, so I wrote down their character names, but the Contacts menu isn’t finding them. Is there a way to find them again? (No, I didn’t get their account names; I didn’t think of it.) My follow-up question would be: I can contact them via in-game email, right?

P.S. Yeah, they might not want me to find them (I think I held my own!), but here’s hoping…

Yes, I’m a Warrior. I forgot about my Signet passive buffs (I didn’t “unequip” those). I wonder which one I just started using…? Or maybe it is a Trait I just amped up… I’ll have to check. Thanks!

A couple of days ago, when I logged back in, I noticed these strange yellow “bubbles” drifting off my Norn, all the time. I stripped him of everything and they still showed up. Anybody know what they indicate, if anything? Picture attached. I like to pretend it’s BO because of his heavy armor, but still, it’s kind of distracting.
