Dear MarcoPolo,
I can perfectly understand that you do not want to ban all other filehosts from your website. On the other hand you have to understand that it is
proven that you will very significantly increase the sell of premium accounts if you use one hoster. I can even assure you, that many users
feel better if you select one main host for your files because the "hoster-hopping" is annoying for them -nobody is willing to buy 4 premium accounts for 4 hosters, but very likely to choose "the one" you finally selected.
My suggestion would be to develop a second website or blog were you
work with just one hoster - and that should be ORON.
I like to once more remind you that only fools believe that 85% fro new accounts is better than 55% for new accounts and 55% for rebills.
The last program does make you about 190-200% more profit. But I explained that already.
