I assume you got a bounce on this as you got Krzysztof's name wrong
([email protected]). You should have either resent this or
replied pointing out the typo.

Nice...

Please do not type my name. It's pretty impossible to get it right, so
instead copy-paste the tag entirely without changes and addons.

This actually applies to all other tags as well, even with easy-to-type
names.

Please resend.

Best regards,
Krzysztof
