That was an option we had on account; it seems that some places offer cheap hosting but require people to register before getting the file. However, and this is an opinion of mine, I think there are more than enough places asking for personal data on the net, and even though most of the times you can cheat and put whatever info on yourself, some people find annoying the fact of having to register and wouldn´t try the game for that cause. At this moment we´d like to offer the game as directly and easily as possible -you want to try it, ok, just click and there it is-: we want to promote ourselves so better don´t put anything in between the game and the people. Of course, getting more bandwith will cost us more money, but our policy is to stay like until now for as long as we can. I like the fact that people that want to get more involved may use the forums as guests or registered users, but we appreciate every visit: even the most active members started once as casual visitors. You know, the size of the game is probably a filter in itself, nowadays it still takes some time to download 23 mbytes, so when someone shows an interest as to spend that time downloading the file, that´s enough for us, at least until we face bankrupcy
