I've been invited to several OC's, but never received a message on whether it succeeded or failed.

It's this normal, do I need to stay online?

I know you need to stop doing felony's to start it but other than that.

Pretty sure the alert of what you got deletes itself after x amount of time - because I just went to look and all of mine are gone. 

Anyone idea after how much time it deletes the message?

Also more importantly why does it delete itself?

Seems to me like it's deleted after you've been in your personals, but I suppose i haven't checked whether it's a certain time to it. 

You should get a notification in the lower right hand side of the screen if you're online though. Not sure why it's deleted.  I wouldn't mind having it as to own category on the personals. :p
