I not sure if this is just a problem on my board but sometimes when I reply to a PM, after it send me back to 'my profile' it delted the PM i just replied to. Anybody else have this problem? Im on 7.4

PMs that you reply to are not "deleted", they're simply hidden for the time being. Ted hasn't completed the section of the PM system where you can view older PMs yet.

ahh, ok. Good to know, thanks
