The sig file is OK, though I prefer 5 lines in succession as a max, with no spaces. Takes up too much of the post area, IMHO ... but it's OK. Also don't mind if you link to your own websites or blogs, just no affiliate links.
I did have to clean up your JV Offer post, as we don't allow outgoing links (we include a link to your JV Page in our iFrame, which you're allowed multiple instances of) nor over sized fonts. The JV Offer letter should look as much like our Premium JV Announcement mailings, format wise, as possible (archives - http://jointventures.jvnotifypro.com) ... I also made a few spelling corrections and opened up spacing a bit, new paragraph wise.
I also went ahead and made your calendar listing active for posted JV Offer (as a VIP, your first listing is free). If you want to bank the free listing credit, instead ... just let me know.
