Last time, comments took me 6.78 minutes (and yes, I actually timed it) to load, so try to talk to me in here or on my other project(s, if I ever post more).
Honestly, you don't have to use it, but it would be nice if you want me to respond to your comments, since I could always read them in the messages part, but I once got 190 of them so I might get bored of waiting for comments to finally open or I might not wait long enough to respond. I have learned that through projects the loading works faster, so it is much easier to comment here (yes I know that my previous sentence is a really long run-on sentence).
