Like you and perhaps many others, I don't care much for the fact that some users who make a paid request, receive many responses, then abandon their thread without rhyme or reason. This happens quite often!
To date our Paid Forum works like a contest, it is generally accepted that you risk your own valuable work and time when you respond to a paid request. Not everyone wins the contest. It is a responsibility you take on for yourself. Your work may or may not be chosen by the OP, and under normal circumstances, the OP should not be monetarily responsible for all submission edits placed in the thread competing for the posted job.
We should be adding new rules like 50% advance payments for edits
One interpretation of this suggestion is we simply can't force our requestors to pay all of our forum members who post submission edits to a job, ANY amount in advance! How can we know who the requestor will choose and should be forwarded an advanced payment? We don't know.
Another interpretation of your suggestion is the forum is currently not set up to have the requestor commit a 50% advance into a community pot to be paid out to the chosen freelancer. We simply don't have the resources for that kind of system. Also, some edits are only worth a few dollars. In the event of an abandoned request, the 50% advance would then have to be split among those who participated. There's still no incentive to stop the behavior.
Since PSG is a community forum and not a dedicated freelance service site where members pay a fee for participation in both buying and selling their services, there's no means for the forum to hold potential users who function as buyers or a requestor of service from our Paid Forum, responsible for payment. That has always been between the requestor and the forum member who completes the job.
The very best this forum can possibly offer as punishment for abanndoned requests and their requestors, is banning...............which may not be the best way of handling the issue. Some requestors may have 10 completed paid jobs in which our freelancers were paid, and then slip up on one request that goes unanswered. Who's to say we are not ending future requests that the OP/requestor will happily pay! It's the proverbial rock and a hard place. Of course this does not apply to repeat offenders and those who refuse to follow the Paid Forums rules.
The forum is open to suggestions for making the situation better. Let's hear them.
