At the moment the purpose served by groups on ModDB is twofold. The first being there use as fan / hobby groups whereby say you wish to create a musicians group, 3d artists group or game fan / bashing club you can do so, and you can invite members to join and share their work. The second being there use as game / mod development groups whereby if you have a team of individuals developing or publishing a game or mod, you invite them to join the group linked with the game or mod project. This way the groups members control the linked content, and they are listed as developers.
As of today these groups are officially split into two separate listings. All of the groups developing and publishing games and mods have been moved to the company page, and all of the fan groups and general groups remain on the groups page. We hope this move helps ease a lot of confusion people have had in the past with the groups system. Having said this we know the majority of mod development teams are not "companies" however we felt this was still the best name for development and publishing groups as you will be listed alongside folks like Valve, Epic, Blizzard etc.
In addition to this, groups will now show a blog, while development / publishing companies will list the game and mods they are working on, which we feel is a much better way of presenting the relevant information. We hope you enjoy this rather large enhancement, and if you have any questions / concerns please do not hesitate to post a comment.
Finally, we have attempted to move all development and publishing groups to the company page, if your group has (or hasn't) been moved and we made a mistake, please let us know and we will move it to the correct section. We also encourage you to update your links to point to the new correct urls and to link to ModDB as we appreciate the support! Enjoy.
