excipio fidelis: quingenti epistula

I have tried to bring a bit of Culchah into my blog. Seeing as this is my 500th post. I used a dictionary and tried to write something like

Welcome Friends: Five hundred blogs!

but I expect I got all the grammar wrong. I expect there will be bloggers out there ready to correct me, well poo to you! This is my blog and if I want to say "to enter the people five hundred a letter" instead of Welcome Friends: Five hundred blogs then I will.

Its a bit like that scene in The Life of Brian

CENTURION:
What's this, then? 'Romanes Eunt Domus'? 'People called Romanes they go the house'?
BRIAN:
It-- it says, 'Romans, go home'.
CENTURION:
No, it doesn't.
