I dunno if ya'll have ever heard of MailChimp, but it's a newsletter service that is super user friendly and free to use, and I was just thinking a newsletter might be fun for Pipeline.
It could be bi-weekly or monthly and just have forum news, popular threads, top poster of the month, whatever. I was playing around with MailChimp the other day and made a test newsletter:
You can customize the layout, add social media stuff, etc. It's pretty nifty.
Anyway, just thought I'd suggest it.
