Sellers should have the option to send a customized/personal message when they submit a gig to a buyer request.
This doesn't mean sellers should be able to spam a buyer's inbox with messages and promotions, rather let the communication be open and limited by buyer requests.
Currently, when a buyer creates a request, the buyer has to select a category and sub-category; this selection limits what gigs a seller can offer as a response to the request, often making a seller submit a gig that doesn't make sense to the request because the appropriate gig isn't available for selection. This, plus the generic message (which does not distinguish the offer from any other offer), causes a great headache for both sellers and buyers, and often will result in less gigs ordered.
Last week (before Christmas 2013), sellers were able to go to their inbox after submitting a gig and there be able to give details on why they submitted the gig they did and direct the buyer to the appropriate gig; this is no longer available and the removal of that ability has created a lot of frustration and lashing out at Fiverr for their 'ignorance'.
Before V2 of Fiverr (released for open beta in early July), sellers were able to communicate openly with buyers who made requests. I don't want that (because buyers will just get spammed), but I urge and beg Fiverr to allow at least basic communication where the seller can best present their gig in their own way.
Fiverr's editors, content managers, advertisers, blog writers, and CS ALL mention that communication between the buyer and seller is the best way to make sure there is satisfaction in a product/service ordered on Fiverr, yet they do not give us a means to best communicate between each other. Due to their refusal to allow sellers some sort of way to communicate with buyers, along with the limited characters allowed in a gig description and title, sellers receive many orders which are unreasonable or completely out of the question, then those sellers get their profile hit with negative feedback and/or a high cancellation ratio.
