Hi,
I wanted to put this info on the NAMD wiki, but it kept telling me to go
away.
"Unknown IP address. Please go away"
But rigth below it says:
*"YOU* can edit, extend, or even create any page in this site by clicking on
the edit button."
So now I'm a bit confused as to what I'm doing wrong.
Best regards,
Ajasja
