Read the description though for its limitations. Also note the adaptor costs 50% more than the price of the lens being offered!

Before this thread disappears, I just wish to point out that I got here by way of the recent activity link, without noticing which section it is in. To me it just came across as another forum discussion.
The only way to prevent this is to remove the Recent Activity link but I suspect that wouldn't be a very popular decision if the classifieds were excluded from recent activity.
Whatever the section is called wouldn't make much difference getting here by this means. I'm sure many others get here by the same method and probably have never seen the instructions JR refers to.
I just bookmark recent activity to see if anything interesting is going on and worth commenting on.

Perhaps we shall never know!

Do you mean hot on condemning then or hot on encouraging them??

Probably best to ask Twitter support.

Well if they've all bought one Ricoh won't complain!

Regarding your original question, 1 or 2. It depends on what story you're wishing to say. In a series of lighthouse shots, having the lighthouse in focus makes sense. If it was a series of photos on survival techniques, the pile of driftwood given the prominence might be more apt. As a purely pictorial image, Gareth's third option might be preferable.

Hopefully that survey bodes well. Be odd to see Pentax back as the top brand but who knows!

Yes, try that solution (Lithium batteries) if you really like the K100D, it should solve the battery problem. Should then work with good NIMH's afterwards too. But if you want a new camera, get it anyway, though if you wish to keep the K100D as a spare or sell it on it's good to know it does work as it should.
There are a couple of YouTube videos about this issue (albeit on a K-x) Part 1 here and Part 2 here
