I've searched for it but couldn't find anything. Is there a way to implement co-op to a blog hosted by blogger (so .htm extensions)? All of my sites are php so I have no clue if this would work? thanks in advance
The simple answer is no, blogger does not support PHP functionality. You could always publish your blogger blog on a different host.
Thanks for the answer dcteam. I got my own vps and moved my old sites to my vps. I have 3 blogs (2 of them on blogger), and I want to leave them there for different IP and cross linking. I guess my blogs will not have coops, but I can live with that
