Personally, i took the initiative on registering around 300 open-source projects in Launchpad - since i got both positive and negative reactions of this, and my only concern were the good will on helping on their popularity, and trying to avoid their becoming abandoned projects, i got very enthusiastic with it, and forgot to send mails for their main developers about it - if some problem happened, please contact me. Btw, i think Launchpad social network should be improved for helping this issue, since there are tons of very good projects becoming abandoned, and it's not fair at all i'm being notified as abuser.
