I just added a collection of 363 links to my blog. You will find it on the right side under the title "Herr Zinnlings Links". These are my favourite hobby related sites. I will add more in the future, while others will disappear. (Like Major General Tremorden Rederring's excellent Colonial-era Wargames Page which is only available through the Wayback Machine at the moment.)
I used categories like Games, 28mm and Terrain to group the links. Sometimes a website could have been listed under different categories. To not complicate my life, I just placed it under one category, the one that interests me most.
I hope you find this collection useful.
