Sorry, no idea where this was brought up or by whom, and I swear the search facility on the forums gets worse every day! *grin*
Anyway, somebody suggested recently that putting strokes or obliques in titles would stop items being loaded into Google. I checked this with a new listing last night, and it's appeared in Google Products (Shopping) with no probs at all this morning.
While I'm here I might as well mention this one again, that I tested a while back: While Google does object to all capitals, eBid will transform excessive capitals into lowercase when making the upload - so your item *will* be uploaded, but the title might look a bit odd!
