Am still a relative newbie here, and finding MetaFilter a fascinating source of high quality / low noise information and interesting stuff. But am struggling a bit with writing FPPs. So far, have had 7 go up, but 4 pulled. Stressing that am not complaining; every time there's been a reason politely given why, and I've retrospectively thought "Yeah, that's a fair point." But it would be nice to consistently put up interesting and always legitimate FPPs. I feel a bit that am learning the ropes of doing proper FPPs by trial and (often) error - perhaps have gotten practice on other forums, that are slightly or very different to Metafilter, hardwired into me and it's difficult to spot other than retrospectively when it's pointed out. Is there a sandbox area, or some other mechanism for getting other people to look at one's FPP before it goes 'live', to see that it's legitimate (beyond the clear warnings not to self-promote) in terms of content and style and any other criteria? I have no problem with constructive criticism, peer review et al.
