Unable to post to Premium Theme Support on wordpress.com

[palurie]

Hi Andrea:
I am the webmaster for a client using worpress.com, and have admin access.

He bought Minimum for wordpress.com, and I would like to ask some tech support questions, but since I am only a co-administrator, I cannot post. His WP address is jeromeburne.wordpress.com

Is there a way to give me access?

My question is about the extracts in the Portfolio section of the Frontpage:
1) how to set the basic extract length
2) can I use the "More" tag, and get it to display on the front page (at the moment it cuts off the text, but doesn't display any link)
3) If we use the 'automatic' cut-off for the extract after "x" characters... is there a way to make the [...] a live-link.

==========
Sorry if this request is in the wrong section.

Many thanks
Peter
