Keeping sites and planning them is a nightmare...I have been trying to start mine for about 3 years now
...and I simply never get the time. Plus if a website owner looses interest in ponies then unfortunately they may simply allow it to vanish by the way side rather than spend time and money keeping it up to date.
I dont think I have seen anything for Elite of Ponyland since about 2005 although I still see the little Mimic badges occasionally here and there...as for Dream Valley Court House I honestly havent heard of that one so cant help!
