Yes, multiple times. And in some cases I messaged the person after one or two weeks, they said they were still interested. Time passed, I messaged them again... and then they finally apologized and dropped. Or sometimes they never bothered replying. And yes, they were logging on Subeta. xD
And in some cases, I'm talking about people that are "known" on the CW community (and not about non-experienced CW users at all), so yeah. :)
