I have just thought of something useful i can do over the holidays: upgrade WordPress and investigate K2.
Something really important is to get the OpenID commenting working again, however i have to do that, even if i have to say “please log in with OpenID before making a comment”. K2 looks great, but i’ve just seen there is a brand new 2.5 preview of WordPress which might be worth a go. It talks about one-click plugin upgrades which is something i really wanted from K2. I’ll have a play and see what works best!
