Sometimes I'll read a message when I don't really have time to respond - that just lets me know what the message is about so I can be thinking about it until I get the chance to respond to it.
Now, if it's been like a week since you sent the message, than that's another thing
Not posting on AT as much because Maki/Steeps gave back some of my forums on GHQ. RIP my decade long blog, my blog even had replies from people who are no longer with us :(.
