If i use feedburner for email subscription how often does it email them? Also, can I use my own subscription box? where they enter their email and submit or does it have to be done using a feedburner box/link? thanks.
Feedburner will send updates daily according to the frequency of your updates. If you use your own box, you might need to manually send your own updates. You can customize your feedburner e-mail subscription box though.
