I personally have no idea why someone would intentionally do this. With all the members here, and all the issues, and distractions and problems with focus... and that no one is perfect, we all make mistakes... wow maybe there should be a place to make such a post... without causing an uproar? This type of thing does happen from time to time... members try to work through their own issues, and send PMs and then realize they just can't "handle" PMs or anything, maybe forgetting they still have a response "out"...and shut off EVERYTHING for a break?
IMO it should be perfectly fine to ask someone to allow them to PM (back, if need be)... right now the options are: 1) post it 2) ask a mod to help contact them 3) write it off or 4) wait till you can accost them in chat!
What do you think?
