I have asked this question before, but seemed to get no answer whatsoever. It can't be true that people in that community bever wondered, how come that when you delete an attachment with id 1, and that is the only attachment there is, the next attachment you upload has id 2, not 1. How come? After i delete any attachment, i want it's id to be taken next time i upload something, so that i don't get any non-existing ids. How can i achieve this?
