DoomDb - The official Doom WAD sharing group!

About: DoomDb is a group in Moddb where you can share all the best kinds of Doom WADs out there! (As long as the rules are followed)

Rules:
1- Always credit the owner. You should also link the owner's homepage when sharing (although that is optional).
2- Its okay to share/post updates about WADs that you are making. If you are going to do this though, don't spam the page with its stuff. A picture or link is always enough ;)
3- Avoid sharing Terry WADs.
4- Avoid any kind of serious discussion in the comments. This group is for sharing WADs and having fun. If the user persists then the comments/image could get deleted.
5- Contact the author and ask for permission before uploading a wad up here, unless your uploading wads that give you permission to distribute the file in their readme or if they are very old (more than 10 years). Having their mod uploaded in multiple places by other people can make it difficult to ensure everyone is using the latest version. If you are unable to contact the author, or the author says no, then simply don't upload it.

Top Wads:
Many have debated, many have fought, but there is one source that keeps on recognition to those whom stand out from the rest. It started with Cacoawards, but since then a top 100 wads of all time list was started, to cover every year since Doom's release.

Ports:
Doom 1 and 2 are long in the tooth but that doesn't stop modders from keeping it running on modern systems. Numerous ports that enhance the game to have many options, features, graphical improvements and bug fixes to keep it in tip top shape. The most notable of which:

LZDoom and ZDoom, its offshoot GZDoom (maintained by Graf Zahl), and Legacy (mod compatibility and customization focused ports).
Zandronum (older version was called Skulltag, a cooperative and competitive multiplayer support focused source port)
Samsara (Also a cooperative and competitive multiplayer source port)
Vavoom, K8 Vavoom & Doomsday (advanced md2 model, lighting and hi-res texture ports)
Chocolate Doom (or a similar one; DoomRetro, limit-removing with some enhanced features, both are faithful nostalgic ports)
Chocolate Strife (never had its source code released but this is the next best thing).
