Forum BookMarks Disappeared!!

Hi Mods, Helge Chris etc…I have been keep bookmarks on several topics, as a reference for this forum, but I have just noticed some topics or pages are now missing!!! …for example

was a DJ Crossfading Post .which is now unavailable…can someone please answer whether the admins/server staff are deleting or incorrectly removing topics adhoc>>>…as this would be a severe pain in the arse to realise many MANY hours worth of cataloguing this forum during daily use, for future reference for younger members etc, trying to avoid repeat topics etc…is now folly!!! and been turned into a complete waste of time.

Has somebody in the backroom , messed about with the database>>>.??? :blush: or is it a case of being removed by a member?..
