Which design will be best for your members and you as the owner? Central Site + easier to maintain one site + only 1 license fee + members can move from product to product - maybe incongruent to a member, having to many unrelated topics - all sites may go down at same time Multi-sites + congruent with your niche + if one site goes down, wont affect others (same server too?) - time to update multiple sites - multi license costs Sure I'm missing others.
