While certainly not required, if you make any changes, either improving some characters or adding new ones, please consider contributing them back so that others may use them, I will credit you on this web-site and within the font file as possible.
Please use the following attribution: “Ælbrocan © 2008 Matthew Stephen Stuckwisch” and mention either explicitly or via hyperlink the license (all this is already in the font file), and if possible, link back to this site.
If you are just using Ælbrocan on your web-site, a simple mention somewhere on the about page would be nice, though not required (since all attribution information is in the font file). Same goes for using Ælbrocan in any other circumstance.
