they don't but the problem is that when you go to pull new posts and miss the ones between your last pull and the renumber... let me try to explain that batter...

1. you read posts 1-50
2. your client remembers your lastread as #50
3. the BBS purges the first 25 and renumbers
4. your #50 is now the BBSes #25
5. you make a new pull and your client starts at #50 which it has as your lastread
6. you've missed 26-49 because your client started at #50 and didn't know your lastread had moved back to #25

now consider you want to go back and read earlier posts... so you select #15 but the header your client has doesn't match the #15 you're sent because that #15 used to be #40 (15 + 25 that were purged)...

now consider if the BBS hasn't pulled 25 since it purged and renumbered... when your client requests #50, there is no #50 on the BBS... now what?

does that help to make it clearer?
