I don't think it's being offered "again" but is "still" being offered. I spoke with someone yesterday at My Points and he said that they are working on the More.com point posting situation and that it should only take another week. I also asked if this offer is new and if one can get it more than once and was told, no. It's a one time deal.
Yes, they can be a pain. You really have to keep track of the points that are to post and you really have to be on them about posting missing points, but eventually they'll do it. I get frustrated when points don't post even after the required 2-5 business days but I
just stay on them. An important thing to remember is to save your confirmation emails. When you request missing points they always want that and sometimes it helps to speed up the process when you attached these confirmation emails to your request for missing points.
