(edited based on Ashley's great comments)
I suggest that BPL take the time to reorganize the forums, including combining some, reordering, renaming, and adding one.
This would result in easier navigation, more posts made in the correct place (not just everyone using "G-Spot"), more robust use of the forums, etc. I suggest looking to rename, reorder, and combine forums that confuse folks, to make it all as logical as possible. i suggest deleting Reader Tips and On the Web, and moving relevant posts to the appropriate remaining forums.
Also, the current front page for the forums is a full SEVEN pages long on my computer screen - much too much! This could also be helped by making the descriptions under each forum more concise - they should be rewritten anyway (needlessly long and/or jokey, not a proper description of the forum contents, etc.). And any way to eliminate unnecessary white space would help folks see as much as possible, without hitting the page down key five times or more.
I would suggest the following structure, in order, naming, etc. (see notes regarding changes):
Gear (put at top!)
The Gear Spot (not “The G Spot”, includes relevant Reader Tips))
Reader Gear Reviews (move here)
Make Your Own Gear (includes relevant Reader Tips)
General Lightweight Backpacking
Philosophy and Technique (includes relevant Reader Tips)
Nutrition and Hydration
Backpacking with Family (create this)
Backpacking with Scouts (include Philmont here)
Mountaineering & Alpinism
On the Water (rename, also include Packrafting and Fishing here)
Pre-Trip / Trip Announcements / Hiking Partners (before Trip Reports, logically)
Post-Trip / Trip Reports / Photo Gallery (combine with photo gallery)
Chaff (I would delete this, myself!)
Outdoor Retailer (move section down, or only show link current year?)
Six summer/winter update sections!
Admin (move section down to bottom, and reorder - admin shouldn't be first! gear, etc. should be first!)
