I have just added a fourth user to my test forum. While the first three users have the IDs of 1, 2, 3 respectively, the fourth user has the ID of 10 instead of 5. Is this normal?
Perhaps this has something to do with the fact that upon a time I had a few more users on the test forum (they since been all remvoved though)?
Do user ID numbers adjust themselves to reflect changes after certain members have been deleted? For example, does Jack (ID#10) become ID#9 when Peter (current ID#9) is removed?
