If I get questions I usually post them, as they may be things I have overlooked in the listing that other potential buyers might be interested in. However, sometimes the person asking the question might provide an email address or other personal info if they want more photos - then I would never post!
So nice to hear that there are considerate sellers like you two~ Now I specifically say if they choose to email me the photos instead of posting more on their listing, then let me know so I will message them my email address. Because I have had sellers reply to my questions and post to the bottom of the listing while my email address is clearly written on the message!!! Been burned...I don't post if it contains personal information.
