Weclome
From Homestar Runner Wiki
In 2 emails, the "Welcome" banner was misspelled as Weclome.
This misspelling later appears in Malloween Commercial, on Homestar's doormat. Possibly (though unlikely) as a tribute to the great Scottish comedy, Still Game, which based a season one episode on the purchase of a Weclome doormat.
In an episode of G4TechTV's "Pulse," they interviewed the Videlectrix CEO (Matt in disguise), who greeted them with a hearty "Weclome!"
In Homestar's Website, the DVD commentary for Tis True, Pom Pom, Tis True, and the Screen Savers Interview, it said a similar phrase: "helscome".
