My b2evolution Version: 1.8.x
I set my blog up to generally use the long version of URLs with the title (mostly) included in it. There is a shorter version with just a page number available. It seems that both are actually available all the time, but that the blog uses the long one in many links. The full index feature which I added in from someone's advice uses the page number.
Because long URLs are generally a pest, I was thinking of changing my blog settings to use the short ones by default. That also would mean just one type being used as I am getting those on the index.
Are there any considerations on this when making the change? I don't want all my old posts to suddenly vanish without trace. Is it possible to make the permalink use the short URL with page reference? I thought there was a tick box for that but now that I look I can't see one.

The "full post index" page that I created also reflects these urls instead of the post number ones you generate.
eg: http://wow-factor.com/index.php?disp=postindex
For the full post index page I use.. (Note: example is limited to 400 posts but I see no reason why it can't be any number)
