When I exported my posts I noticed that some of the ID numbers were missing e.g. it started from 8 and went to say 21 and then from 24 to 30 etc. Is it possible to reuse IDs 1-7 (or any others that are not shown in the export) as they're obviously currently not being used? Or is there any way to clean up the database so that the IDs start from 1, 2, 3, 4 etc? Thanks in advance for any help you can provide.
