Here's what I believe the 'perfect joinpage' might look like:
Why?
1. The page is geo-targeted in as many languages as possible, with a "revert to English" (and other languages) option available in all countries to capture the travelling businesmen and expat markets.
2. Welcoming text with reference to the site to maintain association. There are no pics since it is not permitted to include near VISA and MASTERCARD logos since this is deemed to be "Brand damaging"
3. All credit and debit cards accepted for trials, membership and yearly/lifetime membership.
4. Premium SMS for trials in those countries that support it
5. Phone billing on both a 'buy time' and pay-per minute basis
6. An easy to find "want to cancel?" button - by making it easier to cancel, you are making it easier to join
7. 24/7 freephone and email support
Anyone care to elloborate?
