I was able to "reply" to profile posts pretty easily a bit ago. Is it done with @Username now? Sorry if I'm off base but all I seem to be able to do is "like". Thanks ahead of time for the help. EDIT: Also I totally just referenced a new/dormant user as example. Sorry, Username!
Well, I'm officially blind in both eyes. There were just a few users that I couldn't do this with. I guess it can be enabled/disabled from their end? Sorry for the stupid question.
Some users disable it unless they follow you. to edit your settings you can go to http://assemblergames.com/l/account/privacy and find "Post messages on your profile page" Hope that helps.
