I am sulfur, a Wikian since early 2006. I usually contribute on Memory Alpha and occasionally on Memory Beta, occasionally visiting other wikis. I was part of the VSTF for several years, helping to clean up spam and vandalism throughout Wikia.
If you want to contact me (for any requests, questions, or elsewise) you can leave me a message on my talk page on any wiki I've edited on.
Please see my user page at Memory-Alpha if you really care. :)
