Here are my $0.02 on the matter:
A thread with this type of information isn't necessarily the best idea. Yes there is some general information that should be available readily, but I think most of that has already been covered. For more extreme cases I feel that individual threads about x, y, or z are much better for a few reasons.
Many times that a snake is injured or becomes sick there is a reason why it happened. In a general thread about this the source of the issue might not be made apparent to the user and thus the issue wasn't actually resolved. Treating the symptoms and not the underlying issue will likely result in either the treatment not working, or the issue reoccurring. If that user creates a new thread with the specific details other users will usually ask questions and find out what went wrong. No matter how hard you try you just can't write an all inclusive thread on this type of stuff.
Then there is the issue of user experience. In some cases I would recommend totally different procedures to an experienced keeper than I would to a newcomer to the hobby. This goes for husbandry as well. For example I would never recommend to a newcomer to house 2 BP's in the same cage, but I feel that an experienced keeper can make it work with proper caging and procedures.
Finally there is the issue of user misidentification. The last thing you need is have someone treat a snake for the wrong thing. For example scale rot and a burn can look similar, but they require different treatments, and they are caused by very different things.
All in all I would be very cautious about writing a thread of this sort. I would much rather see a thread about identifying problems and what might be causing them, basically a critical thinking exercise. I feel this information is more useful and has less potential for things to go wrong.
