When people change their sets...

[Zero!]

Not really, unless numerous people have really similar sets.

*changed set, will probably confuse people, ahahahah*

For the most part I don't get confused when people change their sets. I have a pretty good memory, and I've noticed people either change their sets once in awhile or very very often, so when I see it once, I remember it.

Sometimes, yes. I usually remember a set going with a name, so it isn't always confusing. That reminds me, I should get a new set soon. Well, off to find more Futurama pics.

[Jasujo]

Sometimes. It depends on what they change their set to and if the new one has their name on it or not.

When people change sets, it confuses me to NO END. I don't usually look at usernames, being able to tell who it is just by the set (usually just the avatar), and I can't do that when the set's changed.

Of course, if the sig has your name in big honking letters, I'll obviously be able to tell it's you :D
