I don't think it will confuse anyone if we precise in the OP that the last table is the complete and most updated one.
(maybe an alternative solution is to keep the closed one at the end or in a separate table if anyone interested)
Personally I want to know all the previous campaign since its start
When you're interested in a campaign that has been closed, you can try doing a Google search, just add a Bitcointalk at the end (e.g. Xotika.TV signature campaign bitcointalk). This way, you can easily find it and Mitchell doesn't have to keep all the links and records of the closed campaigns. It's a win-win for both parties.
