Contested deletion

This article should not be speedily deleted for lack of asserted importance because... I am still learning how to add information to the profile, including accomplishments,press releases, etc. I wanted to start the page and continue to add to it. A note should be made regarding timeliness. Specifically, should a list of referenced accomplishments be aged? Should an activity occurred more than one year or more ago? The lack of specificity creates ambiguity especially as it relates to other businesses, sites, people, etc. who would like to be included in wikipedia if for no other reason than posterity's sake.

We need two or more independent and reliable references with substantial coverage of the topic.  This is an encyclopedia so that old activity is just as important as recent. So there is no need to restrict information from the last year.  You can develop a page at
