There has always been a time limit (varies for each some forums) beyond which the poster can no longer edit the post. This is in place because believe it or not people like to rewrite their post after the fact to rewrite history after stirring up discussion
If for some reason a post needs to be changed and you can no longer edit it you can ask a moderator or me to do it.
Thanks for bringing this to my attention. I think it may have something to do with the switch from daylight saving time. I am changing the time limits which does fix the issue. I have to do it manually for each forum so it will take a while until they are all updated.
This Google Custom search may do a better job of searching the forums for some keywords than the old forum search does. The results do not include threads from the Asset Managers Forum however. To search that forum you will need to be actually in the Asset Managers Forum and you will need to use the old forum search below.
