hi vivre,

this is what i'm doing :
1. went to my apartment management and asked them to produce letter of permission for byond dish installation.
2. once they produce it, you can fill up the form in astro web site for byond application and at the same time the letter to astro
3. once u did it, call astro call center for confirmation of letter faxed

this may take a few days but if you always update by call them, your application will be given prioritized.
