Hmm, I'm not quite sure what I have that would fall under credentials, but I do have plenty of experience in actually playing fighting games and have been using SRK Wiki for over 5 years for games like CVS2, SFA3, Garou, MVC2, 3rd Strike and others. Having found myself here many a time over the years, I feel that I have a good understanding of what information is vital to the creation of an effective wiki and how said information can be presented and organized to be accessible to even the most casual of players. With more time allotted to me in recent months it would be much less difficult to try to keep the site as up-to-date as possible.
Moreover, I think it bears mentioning that one of the main goals in creating an account here is the updating of the Melty Blood content on the site. The game has changed to the point that much of the information (frame data,attack properties and even movelists)presented on the wiki is no longer even close to relevant. Even the information on other wikis is no longer relevant and is not updated regularly enough with solid information to be satisfactory. The most up to date version of Melty Blood has recently been released on PC making it much more easily accessible to anyone that wants to play it (as they no longer need to get have an imported copy, burned copy, swap magic, JP PS2, etc.) so I feel that if ever there was a time to create a page for the updated game it would be now, while the game has somewhat piqued the interest of players in the community who might be curious to learn more about the mechanics of the game and different character's play-styles and tools beyond what they might find in match videos.
