It would be a great and very effective feature for each user to select which sections/deals/companies they were interested in, and as soon as it is posted on HUKD a mobile and email is sent informing the user.
User picks keyword 'Dell'
Admin posts Dell deal on front page
Some magic script emails and texts said user.
Said user checks website. Bags a bargain!
I'm not experienced at all in the vagaries of programming such scripts but it would be a popular feature I imagine. Text messages themselves while saying 'HUKD alerts you to a new 'Dell' deal' could also be open to sponsorship, as an additional revenue fund (although might go against site philosophy?). Emails wouldn't be as expensive to send I imagine, if the script was set up.
Anyway, just a suggestion. Like the sub-folder asks.
