Ok, that's fine.

I remember you said you wanted to do it. But it's been for a long time.
I thinks that's why Vlastimil sent the series out. 

You could've said what you've done or your any update when you reviewed
this series yesterday, which wouldn't make others confused. So keeping 
update would be better.

Thanks.
