OK here's my opinion,
as long as a signature is not offensive (to the masses) then what is the problem, now if the signature had been death to all non christians that would be offensive, but praising a god you believe in I see no problem with (as long as its not just to get sales). There is a fine line on this activity and it should be deal't with by the moderators on a case by case basis, this is what they are there for. My personal beliefs will remain mine, but you can be assured this is an objective view point.
OH yeah and the real danger to this forum, so many others seem to be popping up at moment, is over cencorship and the lack of control over some people who seem to invade everyones sale threads with negative comments, otherwise I think its pretty good.
PS I think the price a little high, but a good name, good luck wiht the sale Aguss
