1 - Warning page leads to main page leads to two gallery pages is always a good set up
2 - what you feature is really up to you, but try to keep it to the same niche - meaning don't put a blonde babe getting fucked up the ass in one & a black babe sucking black cock in the other.
3 - my rules is "Free sites with movies must have a minimum of 120 seconds worth of movies & the movies must be at least 10 seconds in length." & I think that's pretty common or similar to others.
4 - as long as I can get the movie to play on my system, the file type is not really important to me
