I've got two ideas for Vodahost
1) Have .fr domain names (for french people like me), even though BlueVoda is in english
2) Have a button in the guestbook to delete all of the messages, because a couple of weeks ago there was no anti spam thing, so I've accumulated spam since april, and I'm deleting them right now and its taken me half an hour to delete about 10% of all the spam AND ITS A WASTE OF TIME, there are 2,5MB of spam (text only!).
So please consider these two ideas.
Apart from that, Voda is great!
