Misuse of Profile Comments....aarrgh!
I usually use the mobile app which does not support notifications for things like profile comments. I pulled up the full web page site today to do a search (because the mobile app's search function suxs)...and discovered a bunch of notifications...many of which were profile comments intended as messages to me.
Please don't use profile comments for this purpose. Send a PM or better yet post a public comment so all can participate...that is after all the purpose of a forum!
