So...the member# is the primary key, but when a member id deleted and the database is reindexed the numbers will compact and filll the empty spaces? I see that threads no longer displays the member number, which is great with me 'cause some were getting it mixed up with our club membership number. To be sure I get it.... our member#'s are up to around 4000, but many haven't posted or visited for some time('tho I cant really tell with a lot of them because the 'last post/visit' didn't import and shows only the registration date), I want to go thru the member list and weed out non-club members who have been inactive for a couple of years or so, then optimize the database and the member#'s should fill in? I'm probably just confusing myself, too... Thanks, Tim
