Ive been waiting for a month for it to supply me with something. I just assumed it was dead from a lack of interest, as I've mostly heard negative things about the quality of comments there since.
It is glitching for a lot of users, so now they can't use it, and that's why there aren't many stories in it at the moment. It's best to try and change your criteria or just wait until the update.
@ Tygra's Kitten Kori Yea I noticed that a lot, it works about every so often lol For a minute I thought i was worried that i was the only one the Comment Swap wasn't working for. Can't find the Criteria your looking for my butt lol
The Comment Swap feature has been glitching a lot lately because I've submitted two different stories for it and they didn't get any comments. It's best to either wait it out or don't bother with the Comment Swap feature until the Update for it comes in.
