I do agree it's frustrating when the thread just stops. It's good to help people and it should be unconditional, but it's also nice to have appreciation; which I think in most cases happens on the TBar.
That said we do have to consider that some people using this excellent forum who just cannot respond to the thread in a reasonable time frame to keep the thread updated to its conclusion. However, that doesn't excuse them from concluding the thread at a later date.
A lot of the information within the T Bar is historical, but still very relevant, but it just needs a search through the files rather than a "new topic" created.
Personally, I prefer to search for the information myself or work it out on the job, but willing to help out with suggestions if I feel what I know is useful.
I have noticed that comments on all the forums do tend to die off during Autumn and Winter and resurrected in Springtime. I suppose this is relative to the cars being in use, and not laid up.
Now I feel that I'm moaning so I'm off for a double Southern Comfort with plenty of ginger ale.
