Sign Overload at RoadSignMath.com

RoadSignMath.com (RSM) was a near instant success and consequently the RSM Administrator (RSMadmin) is suffering from the "sign, sign, everywhere a sign" syndrome. The following was posted to RoadSignMath.com on 23 January 2007.

   "Hello faithful fans of Road Sign Math! I'm here to give you all 
    an update on the future of our wonderful driving game.  Anyone 
    that frequents the website will notice that sign postings have 
    dried up almost completely. This isn't for lack of signs being 
    found, I have about 50 of them in my incoming mailbox.  It is 
    however just a pure lack of time to do the work. It takes 10-15 
    minutes as it stands to post a single sign on Road Sign Math. 
    You can do the math...  15 x 50 = 750 minutes = 12.5 hours"
    
    [...]

    "Remember:  driving + math = fun"
