Adding Darrb to e-commerce web sites definitely would be a great plus for you, but since the members base have not reached critical mass, big players might be hesitant.

So for a start you could do it with small e-commerce sites.

and the best and the most cost effective way to grow members and create a brand for a startup is PR, which is FREE.

I recommend you contacting TechCrunch, Mashable readwriteweb, CNET, Redherring..etc. you can email me to get some tips ( when you do plz mentions AC to them :).

By the way i did a quick googling and have not found any one doing what you do is there any?

further more i recommend you to use Shipping 2.0 as a slogan and may be find out if you can TM

focusing on the points you mentioned on how to improve darrb.com, many of them where actually in mind, but we thought it would be better to wait and see the reaction of people and how they use the website before taking any further action.

for example, we didn’t even think that people will use darrb.com for “purchase+deliver” items. if you see, many people ask for someone to buy them some items from their countries and deliver them to their country by normal mail!

i had the multi darrber idea from the beginning, but i thought lets wait and see how people use the website, especially that the idea needs a lot of thinking on how to actually make it practically feasible.

The SMS and GPS ideas are also great, we should look at those options when we charge membership fees in the future (no plans to charge anything in the near future).

Integrating with other marketplaces is my dream! i wish we could make this happen soon. since our concept is very new, we are focusing on increasing the number of items being delivered and making the process of adding items easy for people. this step will pave the road for integrating with other marketplaces:)

Many Thanks again for the review.. i’ll be very happy to see other comments and how we can improve the way we work.
