My $0.02... likely worth less.
Sub-forums are always good for those who know what they are looking for. But as noted higher in this thread, the beauty of enthusiast forums like this is that you can be idly scrolling through a forum looking for nothing in particular and stumble upon something that you can really use but never knew you needed. So is it possible to have it both ways? In other words, there is a overall forum header that holds all the posts and then below that are the sub-forums that are sub-categorized by topic.
An even greater need in my opinion is to have a place where "how-to's” are listed (preferably as PDF files) and made sticky and read only. As a new S10 owner and new forum user, so often the hard part of finding what you want here and other forums is sorting the signal from the noise. For example... I recently needed to spoon on new tires as I have never dealt with a bike that has a final drive before. Sure enough there are tutorials available with pix here at the site for both front and rear wheel removal and replacement. The first post has the bulk of the info and some great pix. Then many pages of subsequent posts later we find ourselves talking about divergent topics. Of course among all these later posts are scattered nuggets of info that are key to the wheel removal and replacement process. But the very fact that they are obscured by all the noise deep into the thread makes them hard to find. This is true of about any thread as they almost all unintentionally (or intentionally!) get hijacked.
I am well aware that this website is administered by volunteers so I am not suggesting more work for them, but at the same time the S10 community is populated by people who are quick to share their knowledge. So would it not be very nice to have an easy to search section devoted exclusively to specific mods that offer easy to find downloadable PDF files that held only the very important info on the instructions, specs, and pix of any one project?
Maybe we could ask for S10 forum volunteers to step forth. Each volunteer could look at the list of mods that would be most useful and pick one to do. Then that volunteer could do a forum search to gather everything he/she can find on a particular topic and then distill it all down into a simple MS Word document. Then this document could be submitted via email to a panel of 4-6 very experienced S10 riders/mechanics to vet these documents for accuracy and completeness. Once the checks have been made, the document would be converted to PDF and posted to a section of the web that is not a forum per se, but more of a library of documents that is read-only so we keep the signal to noise ratio high.
I know that this can work as I have been party to other enthusiast forums where it has been done very well. The KLRWorld forum comes to mind as being particularly effective in this respect. Again this is just a suggestion. But since I made it and if this thing gets traction – I will step up and volunteer to put together the documents for the front and rear tire removal and replacement that I recently used.
