B&S Ratings - I know, I know but this is a bit different
 

I noticed a lot of sellers aren't getting feedback left for them.

ie. you know who bought an item, as posted in a thread (by the buyer) but they don't post any feedback for the guy.

It's really too bad because any diligent buyer will want to check feedback to have an idea of the type of person they might be dealing with.

Is there any way to encourage feedback on top of PMing after a sale, stating you left some for them and leaving a link to your thread, so they might do the same?

I know you guys are working on a new system but it seems as though, while the old one is on hiatus and not getting updated, people are starting to forget about it and not using it.

Thanks

actually the current old feedback archive was recently updated
just send them a PM saying you already left them a fdbk and you would appreciate it if they did the same and then leave a link?

it works 9 out of 10 times for me

This is what I do on most occasions.
