Links wasted

If I change my domain name are all past link exchanges wasted?

 

Yes, unless you redirect from your old domain to your new one

 

with a 301 permanenty moved redirect (I am the yfsbot in disguise completing my own sentences)

 

huh?

If I redirect the old domain pages to the new domain pages - I'm ok?

 

with a permanent redirect, yes. Send this in the header using htaccess or php pr something.

 

probably the best thing to do would be a mod_rewrite to redirect all old URLs to the corresponding new ones.
