pingdotfm is an invalid yahoo! user id

I am having the same problem, it says "There was an error in the server while trying to add a contact, please try again, I do and no luck, anyone have any suggestions, thanks all

No suggestions...I'm having same trouble as Davep

Same problem here. Using Yahoo Messenger 3.0 beta 4 on Mac OS X 10.5.6. Tried using the name "pingdotfm" and tried using "pingdotfm@yahoo.com". Always says "pingdotfm is an invalid User ID"

I went to Yahoo Mail online, added Ping.fm to my contacts, including the Yahoo Messenger ID, and now it shows up as online while I'm logged in to Yahoo Mail. I sent my verification code thru that interface and received the response.

I tried using Yahoo Messenger App on my iPhone...not in my contact list there. Tried manually adding it. Nothing happened. THEN tried sending a message and manually entered pingdotfm as the recipient...I got a response from the bot
and sure enough, my message posted to Twitter, et al as it should. Tapped the Add Contact button, but no pingdotfm in my buddy list.

I then returned to the Mac version of Yahoo Messenger and conducted the same experiment...success! When I manually message pingdotfm, I am told that this user does not appear in my contact list...when I click the button to add I once again am told that "pingdotfm is an invalid User ID"

So I CAN manually send messages to pingdotfm using the Yahoo clients, but I still cannot get the bot to show up in my buddy list in my Yahoo Messenger app on my Mac or iPhone.

How about the Windows Yahoo IM client? Anyone care to try this experiment there? Or is this problem limited to Macs and iPhones?

Im having the same problem as everyone else here.

I have the same problem

I cant seem to add pingdotfm to my yahoo buddy list either. Im using Meebo and i have also tried using the yahoo!'s online web based yahoo! messenger and it just simply wont add it.
