On another forum that I frequent, they have a thread reporting sightings of other forum members that they spot out and about (excluding organised golf rounds obviously). I'm not sure how often it would happen with us, but let's see how we go.

On Friday, I saw andylo with his $1700 camera taking photos in Brisbane CBD. His showpiece was some blurry photo of pigeons.

A few weeks earlier I saw BrisVegas riding his bike towards home from work on the Bicentennial Pathway along the Brisbane River, while I was running home. We chatted while he rolled with me for a bit, before our paths split.
