Firstly I've been occasionally spying in for the last couple of weeks and have to say this is the first thread that I personally have found interesting so thanks.
This is primarily a Q&A site so the requests for PMs, like buttons, more personal info etc defeats its objective IMO, there's already too much exclusivity going on and certainly think the requests to shove the puzzlers off elsewhere is cheeky.
I would like the preview back, it was available when I first joined. For some reason typos are more visible, must be a brain thing.
