I did a post sometime ago about posting IDs. Please note that I posted my OPINION and not the policy of the board.
I know that some people here do share their IDs with those they know and trust on this thread but remember that this is a public forum and you may not want everyone to know your ID.
I suggested that if you want to share your ID with a poster, do it by email or PM. Again, that is just my suggestion. Personally, I am soooo glad I gave my ID to Mrs. Snowgod because she caught a MAJOR faux pas on one of my listings today. Nothing like another pair of eyes!!
I like checking other's lists for something to buy. Nothing like buying from a DIS friend! Of course, I get outbid but, oh well! You never know why someone may be checking your list, so I would err on the side of safety.
If you think I should check with the WMs about this to make a policy of on this, let me know.
