I'm Kinipso, a moderator at http://eldersouls.com/index.html, who has been blessed with the task of outreaching to my fellow TES fans.

Anyways, we're a TES fan site and community that has just very recently began launching TES:O related features (forums, news, articles, etc.). Our most recent and substantial ESO addition is our http://eldersouls.com/groups/; although still technically in BETA, today we decided it's far enough along to begin inviting some guilds to try it out! With this in mind, I have come to see if any of you would be interested in becoming early-adopters of this database to help us eliminate bugs and other issues.
Those of you who are familiar with fan sites such as TESOF and Tamriel Foundry are probably aware of guild lists. We're going to be similar in the sense that your guild will have the potential to gain a large amount of exposure by being listed. However, I also feel that our database is a bit more in-depth in other areas than those seen on other sites. We offer quite a few http://eldersouls.com/guild-features that allow our application to transcend from being just another "guild list" into an organizational home for each guild.
We're offering each guild several administrative options such as custom ranks, page layouts, design, and more. Each guild also receives their own forum, where different topics can be created (as opposed to the single long comment threads seen elsewhere) and moderated by guild leaders (as opposed to solely site-wide staff).
I won't bore with you with a comprehensive features list; if you want more information you can check out the http://eldersouls.com/guild-features page I linked earlier, or stop by and try it out yourself.
I just thought I'd extend this invitation to those of you who are interested in forming your own guilds. We'd love to have your feedback on our site/database to help improve our system in the future. If not, well, that's fine as well!
Thank you for your time; have a nice night/morning/evening!
