Yup. Just shoot me a PM with the precise link to your posting, and I'll happily torpedo it so long as it doesn't toss the whole thread into cryptic disarray. Initial postings in a thread might well do that. I'll also do edits from time to time on request, such as if, at first unbeknownst to you, that spell checker had seized the reins or, say, a link needs correction or some "link rot" has set in. I don't really yearn for a steady diet of such drudgery, but I well understand.
The Admins thought it best a short while back to disable those edit and delete functions after an hour had elapsed after one of our members had decided in a huff to commence deleting each and every post they'd ever made, thereby basically borking the contexts of many otherwise useful or interesting threads. Frankly though, at this point I'd have no objection to resuming the former unlimited editing period for all users. In the meantime, just shoot me a request.
