What is the difference between a TR, a blog post and a forum post?

Here's how we think about it:

TR's = all backcountry skiing trip reports (small trips, big trips, short description, long posts with epic pix - all are welcome)
Blog = well thought out articles, which may or may not be TR's (Would you like to write a blog post? Drop us a line.)
Forum = everything else (there are several categories so hopefully your topic fits into one of them; if not, drop us a line)
