Yes there are minimums; see
https://forum.oneclickchicks.com/sho...49&postcount=5 for (at least a bit) more information. The key, frustrating as it has proven to be for many more than just you, is that part of the threshold is the requirement for attached,
not merely linked, photos and/or videos, which has kept people who are posting only links in a kind of purgatory, resulting in situations like what happened with that post you referred to: a post being delayed, but then appearing in the thread as though it had happened when you submitted it, thus making it seem that someone else posted a duplicate answer
after yours; actually that "second" post was visible in the thread
before yours, despite what the time stamp suggests...
