It feels weird to say welcome. I literally just got in recently as well.

Now that I think of it, when I get to a real life party and someone arrives at the same time, I also say "welcome" with pride and confidence as if I'm the host just to be friendly and ease any tension.

I know some people love merch but I've never really seen the appeal. If I want to support something I like I would rather purchase their media (artist) or donate directly if they have that option.

I do agree though if there is merch, I would vote for smaller logos.
