Just noticed, that one of the legendary wiki sites, Hammerwiki (Warhammer Online) will merge with another great wiki Warhammer Wiki. Here's their announcement:
Dear Hammerwiki contributor and viewers, it is with great pleasure that I like to announce that our staff from our sister site of Warhammer Wiki has agreed to aid this fellow Warhammer site by helping to merge our content with theirs. In the process, we'd hope that by combining our two communities, we can better help aid and improve our knowledge of the Warhammer universe for all to see and read. Rest assured that the majority of the content written and made in this wiki will be transfered to our sister site Warhammer wiki, and will be kept intact or improved upon by our dedicated team of contributors. If there is anything you'd wish to talk about concerning this merge, please message me at my message wall. Thank you and have a nice day!

I decided post again the list of various Warhammer lore sites (with updates). These are all wiki-sites and feature various knowledge about Warhammer world, games and novels. Sites have huge number of articles covering timelines, armies, races, famous persons, sites and places, items, magic, religion...etc.
