For users who aren't logged-in who are visiting a per-site-meta, there's a box on the sidebar that tells them that they need an account to use meta:
(Most sites use 'Welcome!', Server Fault is the only one I've seen so far that uses 'Greetings!'.)
On Super User, however, the sidebar reads:
Ack! There's no exclamation point; this is inconsistent with all the other equivalent sidebars on other sites.
It's trivial, but can it be fixed? I don't mind the inconsistent wording (Welcome! v. Hello v. Greetings!), but the lack of an exclamation point is annoying (to me, at least) and to be quite honest, even if the other sites had the same 'Hello' message, they'd all look a bit weird and cold tasteless.
Compared to the other cheerily-punctuated headings- chirpy, happy, welcoming- Super User's insipid 'Hello' seems perfunctory and a bit awkward. If we could get an exclamation point there, that'd be wonderful.
