was wondering if anyone else was looking at how to implement this... I know yahoo gives like 6mb free and for $20/year you can get 25MB storage... everyone.net also added a premium account with a bunch of other options (more storage, no banner ads, etc..) for $20/year... Has anyone implemented anything like this yet... it seems it's just a matter or processing a credit card and then just updating the user limits, with something to keep track of billing each year... the only tough part I see is whether or not to show ads.. anyone else have any thoughts.. anyone know what percentage of yahoo's accounts are premium, what percent converted, etc... thx.
