Disabling author links on articles

Hi, I'm using your template on Joomla 2.5.3 and I would like to disable the links on all authors in K2 (articles, categories, whatever...). The basic idea is that I want readers to see who wrote that article, but they shouldn't be able to access their "blog" page. Any tips, please?

On a side note, I couldn't figure for the life of me how can a not-registered user could use a gravatar in his comments as I'm testing your template and I can't see anywhere any option to insert an avatar if you are not registered. My K2 setting "Enable Gravatar.com avatar lookup for non-registered commenters" is enabled, but I can't see how could I link my gravatar if I'm not registered.

Please advise. Many thanks!

Hi, you probably need do edit some files in templates\gk_finance_business\html\com_k2\templates\default\ and remove link in autor name.
