Looks like it should be a great weekend.
Bígí Linn agus Bain Taitneamh As!
I hope I'm not being too pedantic, but that could do with a little correction. You've mixed up singular and plural in the one sentence.
"Bígí linn agus Bainigí Taitneamh as." (Plural, addressed to more than one person)
"Bí Linn agus Bain Taitneamh as." (singular, addressed to one person.)
Best of Luck.
Sorry, forgot to post my name in the last post.
Hope my contribution isn't going to cause internecine conflict in the town of the two cabs. :)
It's nice to see the Irish language being recognised and everyone will understand the welcome behind the message anyway.
