After much deliberation and consideration, we have decided that we will be mirroring the existing policies for other games: Mod packs are not supported and will be denied when submitted. Some of the reasons behind this decision have to do with Copyright laws; making sure that permission was granted for every mod in a mod pack is tedious, extremely time-consuming, and error-prone. Another (though related) consideration is the proliferation of "fire-and-forget" mod packs; packs which are slapped together with varying degrees of configuration tweaking and nothing else contributed beyond the work of the original mod authors.
For those of you affected by this decision, we apologize for any inconvenience. Ultimately, however, this action brings our support of World of Tanks in line with our support of other games.
UPDATE: All mod packs which had previously been approved will be deleted on Monday, September 23rd.
