I created a new thread for a post about 18 hours ago. it has not appeared in the forum topic yet. how long does it usually take for a question to be approved and listed? the questions wasn't anything unusual...some code bits and a question on configuration.
There is no time limit on how long it would take to approve a post. However, that doesn't mean it should take an entire day. But the number of moderators is not that high and it does happen that sometimes none of them is around or checking the moderation queue. So if that happens again, send a PM to a moderator. Many people actually post second or 3rd time the same question and they all go to the moderation. If the filter stopped it from being published the first time, it will certainly do the same again and again. So, don't post again, rather PM a moderator (or several).
