what do you want it to do?

to actually post my messages to twitter and plurk?

How far (heh) did you get?

I set up the accounts, it says ok, I post, it says posted, but nothing comes up.

Hm that's weird. Did you try using @ pl (w/o the space) to post to Plurk only?

Nope. Good idea. I'll try it now...

[suggests] you shout if you want a 'quickfire' 1-on-1 session on this issue

I'm not sure I'm that bothered to be honest. I like twitter as it is, and Plurk's posting interface is good (the reading interface is bad).

Same here
