Is mylot deleting?

You can start a discussion about a program you are in. Then if someone is interested and ask for information you can respond with a response with the link. Also if someone is asking about programs in a discussion you can respond to it with a link as long as the link is relevent to the discussion. I suggest you start a new discussion about the program and don't post the link until someone ask for it or is interested.

Yes, they'll delete discussions like that if they see them or if someone reports them. Discussions like that are against the rules, which is why they're deleted.

It is possible that mylot is deleting those messages asking for referrals...I noticed I lost a few responses as well... Nevertheless, its best not to start a discussion or reply about joining programs and referrals....
