VtES Clan Newsletters used to be semi-monthly posts on the "VtES Usenet Newsgroup" that focused on a specific vampire clan (or Imbued) and contained information about strategy, decks as well as a piece of fan faction regarding the clan. The first clan newsletter appeared in 1998, and after a short while quite a number of clans newsletter appeared every month in the newsgroup. I have assembled some statistics on the publication frequency (#issues/month) based on the data in Lasombra's clan newsletter archive:
The heydays of the VtES clan newsletters were the years 2001 to 2004 with an average of 7 or more clan newsletters per month. The decline of the clan newsletters started in 2007, when the average dropped to less than 5 per month. The last two years the release of new clan newsletters almost died down and in the past 5 month not a single new clan newsletter has been published.
